Acetyl-L-Carnitine HCl stands out as a derivative of L-carnitine, offering a simple shift in structure that opens up new possibilities in both application and function. This compound, with its molecular formula C9H18ClNO4 for the hydrochloride salt, presents itself as a white, water-soluble crystalline powder. The addition of an acetyl group to carnitine sets it apart from plain L-carnitine, giving it better solubility and easier movement through biological membranes. Handling this substance feels much like working with common amino acid powders—grainy, nearly odorless, and easily weighed in the lab. The density hovers around 1.17 g/cm³, echoing many small organic acids, and the bulk solid pours smoothly without clumping. Solubility remains high in room temperature water, which speeds up product mixing and solution prep. Most labs and industrial operations that use Acetyl-L-Carnitine HCl look for high purity to ensure it meets nutritional, pharmaceutical, or chemical raw material needs. Hazard warnings are low, but, like any fine powder, good ventilation is a must to prevent dust inhalation or skin irritation after repeated exposure. The HS Code usually entered for customs clearance: 2923900090, covering amino acid derivatives. Bulk storage requires sealed, moisture-proof containers to keep the powder from absorbing water and degrading.
In raw materials selection, Acetyl-L-Carnitine HCl emerges with a practical set of characteristics. Its solid crystalline state means it stores well, ships without extra hassle, and resists most light-induced changes. Heat does not rapidly break down the compound, though keeping it below 40°C extends shelf life. This raw material mixes easily into aqueous solutions thanks to its ionic hydrochloride form. Taste hits slightly sour but not bitter, a point often noted in oral application formulas. Flake and powder forms pour directly from containers without clumping, making production of tablets or filling encapsulated products more efficient. As for pearls or beadlets, they are rare with this material since its fine powder form ensures the smoothest blending with excipients and actives. Density of Acetyl-L-Carnitine HCl in powdered form lets manufacturers calculate accurate dosing and packaging volumes with ease; it stacks well, prevents bridging in hoppers, and reduces overall handling waste.
The molecular structure of Acetyl-L-Carnitine HCl offers more than just a basic backbone. Chemically, it has a quaternary ammonium center and an ester-linked acetyl group, which shifts its bioactivity in both mental and muscular applications. This particular structure increases permeability into human cells when compared to standard carnitine, making it the preferred choice for high-efficiency delivery in supplements and research. Hydrochloride as the counterion boosts its water solubility, letting the product dissolve in solutions made for nutrition uptake, IV compounds, or chemical synthesis. The small crystal shape prevents unexpected settling or caking, which sometimes plagues other amino acid-based materials, especially in humid environments. Molecular integrity remains stable under most routine lab and industrial conditions so long as pH and temperature remain in neutral, moderate ranges.
L-Carnitine L-Tartrate enters the stage as a salt formed from carnitine and tartaric acid, bonding the two into a stable white crystalline powder. Its common molecular formula, C11H19NO9, describes the well-balanced union of an essential carnitine core with the dicarboxylic acid from tartaric acid. Both powdered and granular forms present nearly identical behavior when handled—high flowability, easy weighing, limited static cling. Specific gravity remains close to water because the powder binds with small but significant water molecules, though it remains technically anhydrous. Packing it into tablets, capsules, or liquid drinks gets easier because its fine texture creates a near-perfect mixture with fillers, binders, or sweeteners. The taste veers sour-sweet, much like citric acid, and many find its lemony tang more agreeable in gums or beverages compared to other amino acid stars. HS Code reporting often uses 2923900090 since the product falls under amino acid derivatives meant for human or animal nutrition.
Both Acetyl-L-Carnitine HCl and L-Carnitine L-Tartrate bear low risk profiles but demand respect in large-scale operations. Inhaling any of these powders can irritate the nose and lungs, so proper local exhaust and masks make a difference in daily work environments. Skin contact rarely causes major harm but frequent, repeated exposure may dry the skin or trigger mild redness for sensitive users. Neither product qualifies as acutely hazardous under global chemical regulations, nor does their chemical decomposition necessitate special hazardous waste procedures in standard use scenarios. Eye contact may cause moderate discomfort, similar to dust, so eye protection remains sensible. Ingestion at recommended dietary or supplement levels remains safe for most adults, though some folks with known allergies or intolerances to components—such as tartaric acid—should proceed with medical guidance. Gloves, standard lab coats, and proper containment keep bulk bins and workstations free of leftover dust. Liquid spills rinse clean with just water, as both compounds dissolve easily without forming slippery residues.
In the realm of raw materials, these compounds play leading roles in nutrition, supplement, sports performance, and biochemical synthesis fields. Their versatility in both powdered and crystalline forms helps manufacturers streamline processes, hit precise dosage targets, and preserve functional qualities in finished products. Both store well at ambient temperature in sealed drums or bags lined with moisture barriers, and resist acid-alkali attack, so they work reliably in many recipe matrices. For pharmaceuticals and high-purity applications, rigorous testing ensures metal, microbe, and contaminant limits remain within global safety standards. The material science community values these molecules because of their clean breakdown, absence of persistent byproducts, and low reactivity under typical storage and use conditions.
Acetyl-L-Carnitine HCl and L-Carnitine L-Tartrate—each batch arrives with tight specifications around purity, often greater than 98%. The typical specification sheets detail moisture content, heavy metals, microbial loads, and particle size distribution to support food or health applications. Density specifics allow downstream dosing and mixing adjustments, where a measured 0.5-1.0 g/cm³ pourable solid ensures reliable weight-to-volume conversions. Color should always hit bright white, free of pinkish or yellow tints. Both molecules resist oxidation under inert or air-tight conditions, making shelf-life predictions simple and reliable. Lab solubility tests reveal full, rapid solution in both cold and warm water at diverse pH levels; shakes, drinks, and injectables depend on this to deliver exact nutritional payloads. In fact, the ability to deliver true crystal-to-liquid conversion without residue or sediment saves production plants hours in cleanup and rework. Chemical structure for Acetyl-L-Carnitine HCl highlights a central quaternary nitrogen, carboxyl head, and acetyl group, while L-Carnitine L-Tartrate includes two carboxylate groups linked via a tartrate bridge—differences that inform their role in metabolic support or chemical synthesis.
With solid safety histories, neither of these chemicals lands in lists of major environmental pollutants or bioaccumulators. Their breakdown in water leads to natural amino acid fragments and acidity manageable by routine water treatment. Packaging—usually HDPE drums, lined foil pouches, or food-grade sacks—locks out both oxygen and humidity and prevents accidental moisture pickup. As bulk goods, both ship as non-dangerous according to GHS and major customs frameworks, provided basic dust abatement and labeling. In manufacturing plants where manual handling occurs, clear protocols for measuring, blending, and cleanup avoid cross-contamination between production runs. As more people turn to clean, traceable raw materials, the transparency around their sourcing, testing, and distribution underpins trust in finished products from sports bars to IV nutritionals. Suppliers keeping GS1 or ISO traceability on each drum or lot code support safety recall networks and reassure buyers on both product quality and regulatory compliance.
