(1S,2S)-(-)-Cyclohexane-1,2-diamine D-tartrate draws steady demand from several sectors driven by its unique chemical nature. This material, a crystalline solid, stands out due to its stereochemistry, with both amine groups on cyclohexane arranged in the S configuration. It forms a salt with D-tartaric acid, cementing its place in chemical catalogs under several identifiers. This compound holds a steady spot in synthesis labs and raw material inventories alike.
This compound comes as a fine, colorless to white crystalline powder with occasional off-white shades, hinting at minor batch differences. Crystals grow in compact, flaky, or granular forms, sometimes appearing as pearls or fine powder, each influenced by preparation methods. A quick shake of the bottle, and fine dust flies free—not uncommon in solid amine salts.
The IUPAC name nails down the structure: the cyclohexane ring pairs two amino groups on the 1 and 2 positions, both facing the same stereochemical direction. The tartrate counterion forms upon complexation, linking small organic acids to basic amines. With the formula C10H22N2O6, its molecular weight sits around 270.29 g/mol, making it easy to calculate for lab-scale or industrial recipes.
Roll a small amount between your fingers (with gloves, of course), and the powder shows decent flow. The density clocks in near 1.27 g/cm³, filling vials snugly but not so tightly as to cause compaction. The melting point hovers above 140°C, with decomposition featuring bubbling and discoloration before it melts cleanly. This sensitivity to heat marks safe storage points for large-scale handlers.
Sourcing this material usually connects with researchers and manufacturers focused on stereoselective synthesis. The (1S,2S) configuration turns into a selective tool for chemists needing chiral diamines. In my own experience as a synthetic chemist, matching the right enantiomer opens routes to medicines or specialized ligands, each demanding absolute control over chemical “handedness.” Any misstep can threaten the purity of a pharmaceutical or the accuracy of a catalyst system.
The raw material supports multiple transformations: complexation with metal ions for asymmetric catalysis, pre-cursor for specialty materials, or as a chiral selector in chromatography. Its compatibility with water and some polar solvents shapes how labs prepare solutions—commonly at mg/mL or g/L concentrations. Storage in airtight jars, out of sunlight, locks in its shelf life; moisture sees it turn sticky with time.
Specification sheets demand clear deliverables: purity around ≥98%, heavy metal traces below acceptable thresholds, and accurate measured moisture content. Particle size may drift, but always lands between gritty flow and cloud-like dust, never oily or waxy.
The HS code for this chemical falls under 2921.51, grouping it with other diamines for customs and export tracking. Documentation must list both chemical and trade names to satisfy global trade rules and to speed clearances at borders.
Any conversation about raw material safety needs real honesty. This diamine tartrate sits in the “low to moderately hazardous” group. Inhalation irritates airways; unprotected skin picks up rashes if exposed too long. I’ve had coworkers splash small amounts on bare skin, leading to itching and redness, so proper gloves, goggles, and fume hoods always stay in place. The material won’t combust easily, but fine powders in air can feed dust explosions—so grounded tools and anti-static gear see plenty of use in packing rooms.
Stability remains solid at room temperature, holding to its fine, dry texture in sealed containers. High humidity turns flakes sticky, binding crystals along the jar walls, which signals the start of slow degradation. Far from benign, the packaging process matters: moisture-proof bags, double-sealed, foil pouches, all keep the solid safe on the shelf. Drum containers, labeled with hazard codes, make bulk shipping feasible, each marked clear for D-tartrate content and UN number for safe road or sea transit.
Temperature swings pose little threat unless heat tips above the melting point. I’ve let an open bottle sit on a sunny windowsill once, and overnight, the lower layers fused slightly, tough to scrape out by morning. Proper storage in climate-controlled rooms prevents such mishaps—standard for any warehouse holding specialty chemicals.
As a raw material, (1S,2S)-(-)-Cyclohexane-1,2-diamine D-tartrate finds itself upstream in complex value chains. Manufacturing teams rely on hazard training: handling dust, sealing bags, storing spill kits nearby. Care extends beyond workspaces; waste streams head to incineration or chemical treatment plants never into standard drains. Clear labeling on every jar, drum, and vial limits accidental mixes—color-coded tape, barcodes, and seals cut confusion.
Research into greener alternatives hasn’t outpaced its utility. So, labs recycle solvent and plastic, wash and reuse glassware, and concentrate on minimizing small spills. Awareness grows with every training session, especially for new staff—an investment to keep everyone safe in the supply chain.
Raw material reliability comes from suppliers with strong documentation, traceable batches, and responsive safety alerts. The industry benefits when vendors publish analytical reports, batch purity checks, and testing records. Buying from established suppliers whose products pass strict specifications makes accidents rarer in labs or factories.
Sustainability enters slowly. More suppliers now outline environmental impacts, detailing routes with reduced waste, and lower energy demand. Users who demand detailed MSDS sheets, open records about contaminants, and carbon footprint calculations push the field higher—lifting standards for all.
It isn’t just about cost per kilo; it’s about safe handling, verified origins, full hazard profiles, and chemical reliability from source to shipping dock. My experience shows no shortcut replaces due diligence—an informed approach keeps innovation and risk in steady balance.
