Choline bitartrate, a combination of choline and tartaric acid, brings together two essential chemical components that impact health, nutrition, and industry. Choline, a water-soluble nutrient often grouped with B vitamins, forms a salt with bitartrate to create a stable compound that appears as a crystalline material. The presence of both choline and tartaric acid in a single molecule makes this raw material a go-to additive in food and pharmaceutical production, as the bitartrate form offers good stability and manageable handling compared to other choline salts. Its molecular formula, C9H19NO7, reveals its structure: choline as the cation and bitartrate as the anion. This pairing offers high bioavailability and straightforward incorporation into a variety of delivery forms, including powders, flakes, pearls, solid crystals, and even liquid solutions depending on manufacturing needs.
The physical characteristics define its use cases and handling safety. Choline bitartrate generally crystallizes as white or nearly white, odorless solid, sometimes available as slightly hygroscopic powder, flakes, or small pearls. The compound displays good solubility in water, allowing it to blend easily in liquid formulations or solutions. Density sits at about 1.3 grams per cubic centimeter, which informs dosing by weight or volume. Its melting point hovers in the range of 151 degrees Celsius, which provides practical data for both transport and thermal processing. The material resists ignition under normal handling, though elevated temperatures may decompose the compound, releasing irritating or harmful vapors. This duality—ease-of-use as a stable solid, risk as a heated decomposition source—distinguishes it from some more volatile food or pharma additives.
Choline bitartrate plays a key part in a range of industrial applications. Food manufacturers select it for fortification in beverages, dietary supplements, and baked goods. The chemical’s water solubility makes it a fit for liquid tonics and drink powders. In pharmaceuticals, it turns up in tablets and capsules, thanks to its purity and known molecular structure. With a molecular weight of 253.25 g/mol, formulation scientists can calculate precise dosing, critical for both regulated foods and strict pharmaceutical applications. The compound appears under the HS Code 29239000, marking it as an organic base for international trade—a trade that deals not only with nutritional products but also with industrial raw materials for more specialized chemical syntheses. Importers, exporters, and supply chain professionals track such codes to ensure adherence to customs regulations and safety standards.
Choline bitartrate, despite its essential nutritional status, demands respect in the workspace. Safety data sheets classify it as non-flammable and generally non-hazardous under routine handling. Accidental contact or inhalation rarely leads to severe effects, but standard chemical caution applies. As with nearly all fine powders, airborne dust may cause mild mucous membrane irritation. Overheating or incineration can break the molecule, releasing fumes that nobody wants around unprotected eyes, skin, or lungs. Storing this material in a cool, dry location, away from strong acids, bases, and sources of heat, prevents unwanted chemical reactions. Workers dealing with choline bitartrate emphasise basic precautions: gloves, dust masks, and eye protection. Bulk storage facilities frequently rely on sealed barrels and humidity controls to guard against lump formation and ensure product integrity.
The structure of choline bitartrate, with its dual ionic nature, impacts its solubility and reactivity profile. The cationic portion derives from the choline molecule, bringing a trimethylammonium group linked to an ethyl chain and a hydroxyl group. Its positive charge pairs tightly with the bitartrate anion, which forms from partially neutralized tartaric acid. This arrangement helps the material dissolve quickly in water, proving useful for anyone blending nutrition shakes, supplements, or pharmaceutical compounds. The crystal lattice resists moisture, but exposed samples can clump in high humidity, which matters for large-scale processors more than at the retail shelf. Being a stable solid, transportation and storage costs stay manageable, and the risk of leaks or spills remains much lower than it would with a similar liquid.
Every raw material in the nutritional or pharmaceutical supply chain brings its own benefits and environmental pressures. Choline bitartrate stands out for its relatively clean production process and low toxicity, compared to more hazardous organic compounds. Producers extract choline components synthetically, derived from either natural sources such as soy lecithin, or produced via chemical synthesis. The tartaric acid comes from natural fermentation or grape processing byproducts, tying the raw material supply into food industry sidestreams and the circular economy. Quality assurance labs run regular tests for heavy metals, residual solvents, and competing organic impurities, keeping batches within legal and health guidelines. Sustainable manufacturers have begun to source choline from non-GMO origins and to audit environmental impact at every stage, from solvent recovery in the lab to energy used in crystal drying and packaging of end goods.
Choline bitartrate, despite its long track record, faces a few hurdles. The biggest issue centers on stability under high humidity, which can lead to agglomeration and dosing problems, particularly in climates where moisture sneaks into packaging after long shipping journeys. The most effective answer so far: airtight, moisture-proof packaging combined with controlled atmosphere storage for sensitive products. Manufacturers sometimes add silica gel packets or opt for multi-layer foil sachets to block water vapor. For companies concerned with customs headaches, assigning the correct HS Code and double-checking Certificate of Analysis paperwork at the border can prevent costly delays. With the right staff training and warehouse controls, these challenges get managed up front, keeping costs down and product safety up.
People count on choline bitartrate for a reason: it works, and it works predictably. Experience using this compound in feed, food, and health formulations has shown how its chemical stability and ease of handling bring convenience, value, and peace of mind—not just for large manufacturers but for smaller players who rely on reliable supply chains. The compound’s detailed specifications enable precise dosing in tablets, capsules, or drink powders, which is essential for meeting regulatory guidelines and consumer trust. People want to know what they’re eating or supplementing in daily life. As regulations grow, transparent sourcing, clear labeling, and strict adherence to best storage and handling practices continue to set apart reputable suppliers and keep quality at the forefront of nutritional science and product development.
