(1S-cis)-4-Amino-2-cyclopentene-1-methanol D-hydrogen tartrate stands out as a specialty organic compound with growing usefulness in chemical research and pharmaceutical development. Its importance draws on both its complex structure and unique set of properties. This material typically shows up in solid form, ranging from fine crystalline flakes to slightly coarse powders. The surface looks colorless or nearly white, reflecting high purity and minimal contamination from raw materials or side-reactions. Open the lid of a fresh bottle, you’ll find no strong odor, which is one hallmark of many high-purity organics.
Scratch beneath the name, and there’s a bicyclic compound at play. The backbone comes from cyclopentene, which provides rigidity and orientation for further functional groups. The combination of an amino group, a methanol moiety, and a D-hydrogen tartrate counterion makes this compound tricky to synthesize without specialized knowledge in stereochemistry. Its molecular formula, C12H19NO7, allows precise calculation for lab and industrial applications. Each atom takes up a defined spot; stereochemistry ensures researchers can predict reactivity and downstream product performance. Physical chemists track its stereospecificity, always a key item for researchers driven by chirality.
Pick up a sample, and it feels like most refined organic acids—a solid with manageable density that pours without clumping. Solubility stands out: water dissolves this compound reasonably well at room temperature, supporting both preparative work and pharmaceutical analysis. The density sits around 1.4 to 1.6 g/cm3 based on batch variances, showing suitability for volumetric calculations and certain solvent-based purification strategies. In a dry jar, it doesn’t cake or absorb much moisture from humid environments. Crystals form sharp edges and refract under polarized light, a helpful trait for quick purity checks in field labs with minimal technology.
This compound lands on a bench as finely divided powder, compact flakes, or sometimes as granular pearls. Flakes form during low-rate crystallization, making them easy to pick up with tweezers without loss. Powder settles out of solution after rapid solvent evaporation, giving cost advantages for bulk handling. Some producers offer pearl-shaped granules to help tech staff load precise masses for analytical work. Crystallinity governs how the material interacts with light, solvents, and atmospheric moisture; solid-state purity ties directly to downstream chemical reactivity.
Working with (1S-cis)-4-Amino-2-cyclopentene-1-methanol D-hydrogen tartrate means respecting demands for proper safety. Even organic acids with favorable toxicology can irritate skin or eyes, so gloves and goggles are standard. Though not particularly volatile, dust can cause discomfort if mishandled. Inhalation risk stays low but real in powder-processing settings, especially across multiple weighing stations. According to the latest Safe Work reports, the compound is rated as non-hazardous under GHS guidelines, but each lab or plant creates risk with large scale. With a melting range in the moderate zone (130–140°C), no one runs risk of thermal runaway in ambient conditions or by simple warming.
Trade data identifies (1S-cis)-4-Amino-2-cyclopentene-1-methanol D-hydrogen tartrate with HS Code 292249. This classification eases customs and ensures proper documentation for national and international transport. Shipping follows typical solid chemical materials protocols: sealed HDPE or glass bottles, sometimes with desiccant. Good packaging slows decomposition and locks out water. No litany of hazardous shipping restrictions accompanies small lots, but responsible shippers never cut corners on labeling or manifest accuracy.
Producers begin with petrochemical feedstocks and food-grade reducing agents to build the target structure. Raw input quality determines ultimate product reliability. Purchasers stake reputations—as well as compliance with ISO and GMP expectations—on well-supplied source chains. Downstream processes—synthesis, drug design, stereoselective chemistry—depend on consistency and documented purity. Labs care about both repeat chemistry and trace byproduct exclusion, two factors controlled by skilled material selection at the raw stage.
One issue with specialty compounds like this rests in keeping impurities low when scale jumps from lab to pilot-plant. Researchers notice batch-to-batch variance; results change unless purification stays tight. Modern chromatographic controls help, but rigorous process auditing and digital recordkeeping deliver best-in-class outcomes. Production partners can tap digital batch tracking, collaborative supplier vetting, and new purification resins to further drive quality and transparency. Regulation-compliant labeling and updated MSDSs protect teams across continents. Engineers and buyers work with scientists to choose packaging that fits workflow, minimize accidents, and support end-to-end documentation transparency.
Stereospecificity ties to both efficacy in pharmaceuticals and reactivity in intermediate synthesis. A minor change or contaminant can trigger major swings in final drug behavior or in chemical manufacturing output, so precise structural confirmation matters for anyone in the field. Density and solubility predict performance in downstream solution chemistry, especially as automation and robotics want compound solutions ready for pipetting, not settling out on storage.
The presence of an amino alcohol function, together with a tartrate salt, sets this compound apart from typical organics. Drug discovery programs thrive on molecules like this, as stereocenters directly impact biological activity and the range of reaction types possible. Reliable documentation, compliance with local and international regulations, and clarity on raw material provenance all support higher success rates in synthesis and product commercialization. Facts point to a rising demand for well-documented, high-purity intermediates as precision medicine and fine chemical manufacturing keep expanding.
Buyers routinely ask for confirmed melting range, batch COA, detailed impurity spectra, and clear molecular formula confirmation by NMR or MS. Specific optical rotation and elemental analysis confirm lot purity. Material sold by liter relies on density confirmation reports to convert accurately from volumetric to mass-based specs. Suppliers lead with COA transparency, documented purity above 99%, and customer support staff who attribute issues and sort them before they escalate.
Continuous improvement in synthesis routes, tighter supply chain security, and more robust product specifications see this molecule shifting from obscure specialty to more accessible staple for chemical and pharmaceutical applications. Open dialogue between producers and buyers, recently improved digital tracking, and direct reporting channels minimize error, reduce recall risk, and deliver safer, more performant chemicals. Many of these improvements draw on common sense—track what comes in, know what goes out, and ensure every person in the chain controls quality, not just at the end, but at every turn.
