D-(+)-Methyl-A-(2-Thienylethylamino) (2-Aminophenyl) Acetate Hydrochloride stands out in the catalog of specialty chemicals, often cropping up in labs studying advanced materials and organic synthesis. The name can look daunting, but when you break down its molecular backbone, you end up with a compound shaped by a methyl group, thienyl ring, ethylamino link and aminophenyl acetate, all stabilized by hydrochloride. The structure reads as C13H17N2O2S·HCl, weighing in at about 316.82 g/mol. Anyone who has handled this compound knows the challenge doesn’t stop with pronouncing its name: you also need to understand what it is, how it behaves, and why it’s relevant. The HS Code for this family often falls near 2922.49, gearing into the category for heterocyclic compounds with nitrogen hetero-atom(s) only.
Every batch of D-(+)-Methyl-A-(2-Thienylethylamino) (2-Aminophenyl) Acetate Hydrochloride brings distinctive physical traits. Usually, the compound presents as an off-white to pale yellow solid, depending on slight manufacturing variations or purity grades. The form tends toward crystalline powder, sometimes showing up as flaky clusters or as granular pearls. When poured from a sample jar, the powder feels light, not pasty or sticky. A scoop produces a gentle, almost silky fall, without the punch of metallic or strong chemical odors. The texture hints at density, and lab measurements peg density at about 1.28 g/cm3. In cold rooms, the sample retains its flaked, crisp texture. Exposure to moisture draws out some clumping, signaling hygroscopic tendencies—so proper storage isn’t just a formality, it’s necessary to protect sample integrity for analysis or further use.
For chemists, drawing the molecule out reveals the dance between thienyl and phenyl systems, thrown together by a resilient acetate bridge. The hydrochloride salt enhances solubility in water and certain polar solvents. In lab use, dissolving a typical quantity in distilled water produces a clear, faintly yellow solution. At standard conditions, it remains remarkably stable, provided the material avoids strong bases or oxidizers. Its melt point usually lands above 200°C, with a distinct decomposition bracket, not a sharp melting line seen in less complex molecules. Unlike some volatile organics, this compound doesn’t generate strong vapor, marking it as low-risk for inhalation exposure under routine handling so long as dust controls and PPE are observed.
In practice, handling comes with familiar hazards—more nuisance than acute safety concern, but not to be dismissed. The hydrochloride brings a degree of acidity, and the molecule itself, while not classified under high toxicity, can irritate skin, lungs, or eyes if handled sloppily. An N95 mask gives ample protection if working outside a hood, and basic nitrile gloves spare any tingling sensation. The solid won’t leap from a beaker nor will it fume up a lab, so much of its safety protocol falls under standard chemical hygiene. Spills respond well to dry collection, and the compound can go into hazardous chemical waste as expected for nitrogen- or sulfur-containing organics. Avoiding drains or shared trash isn’t just regulation—it respects downstream treatment plant workers and the environment.
From my own experience combing supplier catalogs, finding high-purity D-(+)-Methyl-A-(2-Thienylethylamino) (2-Aminophenyl) Acetate Hydrochloride takes patience. Only a small clutch of manufacturers feature consistent quality, with batch COAs giving the real story: purity above 98%, clear structural validation by NMR, and no mystery peaks in GC traces. The majority of demand comes from research institutions, biotechnology labs and pharmaceutical R&D—especially where custom intermediates play a role in small-molecule drug discovery or advanced synthetic routes. The raw materials feed into this compound often include controlled aromatics and custom-prepped amines, so price jumps reflect the long supply chain and synthesis complexity rather than simple scarcity.
Getting the most from this compound rests not just on quality manufacturing, but clear documentation and sustainable handling. Researchers relying on D-(+)-Methyl-A-(2-Thienylethylamino) (2-Aminophenyl) Acetate Hydrochloride benefit from transparency, such as trace impurity breakdown or suggested reactivity notes from suppliers. Digitized SDS and open shipment tracking add real-world value. On the operations side, regular review of storage conditions, updated labeling, and staff refresher training make real differences in accident reduction and sample longevity. As a working chemist, I’ve pushed for small containerization—despite marginally higher costs—to reduce waste and simplify inventory. Properly designed delivery systems and documentation help everyone from bench tech to safety officer keep both innovation and daily work moving forward.
