R-3-Ethylnipecotate-L-(+)-tartaric acid salt stands out as a unique compound widely used in pharmaceutical synthesis and specialty chemical manufacturing. Based on my own experience supporting research teams, this compound often ends up at the middle stages of drug-building pipelines. As the name suggests, it features R-3-ethylnipecotate blended with L-(+)-tartaric acid to form a salt, influencing both solubility and chiral properties. Labs and producers looking for high-purity starting materials gravitate toward this product to take advantage of its consistent reactivity and moderate safety profile. In my years around formulation groups, good suppliers always present their product with keen attention to traceability and batch consistency, since minor impurity drifts can complicate downstream results.
Structurally, R-3-Ethylnipecotate-L-(+)-tartaric acid salt features a backbone derived from nipecotate, an ester of nipecotic acid with an ethyl group at position 3 in the R configuration, ionically paired up with naturally derived L-(+)-tartaric acid. Its full molecular formula, C14H23NO8, brings together functional groups that enable both solubility in polar solvents and stability at room temperature. Molecular weight centers around 349.33 g/mol, which means weighing and measuring never feels like working with featherweight fine chemicals. In physical form, this material can turn up as pale, flaky solids or a fine powder. Sometimes, suppliers go the extra mile and deliver it in crystalline lumps or pearl-like granules. Uncommon, but some research teams will dissolve it fresh into a clear, almost odorless solution to streamline dosing in synthesis.
Diving into appearance, you’ll most often find R-3-Ethylnipecotate-L-(+)-tartaric acid salt as a white to off-white powder. This signals good purity, something my old QC colleagues check right away—anything yellowish or sticky throws up immediate red flags for contamination or absorbed water. Density usually sits between 1.15 and 1.20 g/cm³, which places it firmly in the mid-range for solid organic salts. Its crystals neither float on solvents nor clump up rapidly, making weighing and transfer simple in everyday lab practice. Technicians recommend storing it in tightly sealed containers out of direct sunlight to keep hydrolysis and moisture absorption in check. In my experience, the solid feels gritty, and if poured quickly, emits a faint, slightly sour smell, likely from the tartaric acid side. Melting points often clock in around 105–120°C, useful to know for those planning purifications.
Manufacturers deliver R-3-Ethylnipecotate-L-(+)-tartaric acid salt with technical specs including purity, melting point range, moisture content, specific optical rotation, and residual solvent data. Purity runs aim for >98% by HPLC, a spec buyers in regulated industries demand. Water content typically lands below 0.5%, minimizing hydrolytic degradation. The HS Code for this compound falls under 2918199090, the catch-all for heterocyclic compounds with nitrogen in the ring structure, processed as a specialty chemical rather than a bulk commodity. Authorities sometimes ask for safety data, so suppliers need to hold documentation on irritancy, fire risk, and decomposition. I learned firsthand, handling paperwork for international shipments, that missing or outdated certificates create lengthy customs headaches. Reliable suppliers never overlook that detail.
Form matters when planning workflows. The powder form proves easy to weigh for precision batch reactions. Flakes and solid chunks offer better stability during long storage, which teams appreciate during summer months when humidity spikes. Crystals, grown under slow cooling, ensure high purity and lower chloride traces if needed for sensitive syntheses. While pearls rarely feature in this family, they sometimes turn up after controlled drying of larger batches. For some intensive research, dissolved solutions offer quick dosing and reduce dust, but always require fresh preparation—leaving these solutions standing invites slow decomposition. In nearly every setting, the dry, free-flowing powder remains king for ease and reliability.
Practically speaking, density hovers in the sweet spot for tipped scoops and volumetric transfers. R-3-Ethylnipecotate-L-(+)-tartaric acid salt doesn’t cake up if the packaging stays dry. Working with this salt in liter volumes doesn’t make sense outside trial production or specialty pilot lines, but smaller scale research thrives on carefully dispensed grams. Teams handling larger quantities store it in high-density polyethylene drums, which fend off light and accidental punctures. Using glass jars in smaller research environments always works, so long as chemical compatibility isn’t an issue. One real benefit—the lack of static buildup compared to light organic powders—makes for cleaner, no-mess benchwork.
From my years supporting safety reviews, this salt generally raises basic irritancy concerns. Dusty conditions or accidental skin contact may trigger mild eye or skin reactions. Gloves and goggles solve most direct risks. Product decomposes mildly on heating, and rarely puts out toxic fumes under standard lab mishaps, though good ventilation stays important at the bench. Safety Data Sheets point out that ingestion and inhalation avoidance remain basic principles, but overall, it’s never caused major hazardous events at sites I’ve monitored. Still, advice from safety officers holds: keep chemical spill kits handy and label all containers for quick access. As for raw materials, reliable supply chains matter. Untested variants or generic supplies sometimes ship with higher residual solvents or uncharacterized byproducts, tripping up analytical steps later. Good sourcing traces both the nipecotate and tartaric acid components all the way back to reputable vendors, a strategy large manufacturers rely on to keep their product compliant with GMP and international quality standards.
Using R-3-Ethylnipecotate-L-(+)-tartaric acid salt brings both opportunity and responsibility. Its versatility drives applications in pharma and fine chemical synthesis, yielding intermediates with the needed chirality and purity for modern medicines. There’s a real cost to choosing poor quality product, though—I’ve seen painstaking weeks wasted when just one raw material batch failed midpoint checks, forcing process revalidation. Reliable documentation and transparent specification sheets cut down risk. For greater safety, investment in better dust management and regular stock rotation helps keep working areas cleaner and fresher. New tech offers in-line analytics for real-time purity checks, something producers now build into updated QA systems. Chemical transparency, from the raw nipecotate to finished salt, combines regulatory compliance, traceability, and performance—essential for success in today’s tightly regulated sectors. Seasoned chemists and newcomers alike benefit from sharing best practices and careful supplier selection, keeping both quality and safety in sharp focus.
