Androst-2-En-17-One carries weight among raw material suppliers, chemists, and folks working in research labs. Known among its peers as a potent androstane steroid, its formula, C19H26O, lays the groundwork for its use and risks. The molecular structure sports three six-membered rings and a five-membered ring, which matters for binding and reactions. The core of the molecule features a keto group at the 17th carbon, with a double bond running between the second and third carbon atoms. Weight clocks in at 270.41 g/mol, so you’re dealing with a hefty player in the world of steroid chemistry.
Androst-2-En-17-One may arrive as a crystalline solid, sometimes in off-white flakes or a colorless powder, depending on the purification. Density kicks around 1.16 g/cm³, giving it a solid feel in-hand, not airy or dusty like many powders in the lab. Typical melting point hovers in the neighborhood of 145-150°C. This melting point clues chemists into its purity; you don’t want a sample that melts at the wrong temperature, or you’re likely dealing with contamination or a poorly produced batch. Some suppliers carry it in crystalline pearl form, though the market favors material that blends easily for measurement and application. It barely dissolves in water, but slides easily into organic solvents such as ethanol, acetone, and chloroform—classic solvents in labs and raw material facilities.
Androst-2-En-17-One does not float around the chemical marketplace for no reason. Demand comes mostly from research analysts, pharmaceutical developers, and fitness supplement formulators. Athletes and muscle-building circles chase its anabolic properties, though legality shrouds its movement. With legal stakes so high, traceability becomes key, and that’s where its HS Code steps in. For most countries, the HS Code reads 2937.29, under the category for steroidal hormones, which customs agencies treat with suspicion. If you’re importing or exporting, you better get that code right, or face automatic seizure, fines, or worse.
Safe handling never takes a day off, especially with chemicals like Androst-2-En-17-One. Dust exposure, accidental ingestion, or spills can cause skin and eye irritation. Longer-term effects stay hazy, with the potential for hormone disruption if accidental absorption happens through skin. Personal protective equipment (PPE) is no joke—always wear gloves, goggles, and lab coats in any setting where this material is weighed or handled. While shipping, UN numbers, labeling, and hazard statements need visual clarity, or the package likely returns to sender. Keep it well away from acids, bases, and oxidizers—mixing means trouble. If you’re working in a shared materials lab, don’t leave trace residues on balances or benches, because downstream users could carry those contaminants into sensitive experiments or production.
The steroidal backbone of Androst-2-En-17-One determines how the molecule interacts with biological systems. Its planar rings decide which enzymes latch on, and its functional groups direct conversion pathways. Picture eggs and a frying pan—shape matters as much as substance. Chemists often use nuclear magnetic resonance (NMR) or high-resolution mass spectrometry to confirm identity. Even seasoned researchers remember plenty of batches rejected because peaks lined up wrong or the solvents in recrystallization introduced strange impurities—lesson learned about shortcuts for cleaning up raw powder. Structure ties right into the material’s effect, legality status, and shelf life, so anyone ignoring this can end up with useless or even dangerous stock.
Spec sheets tell you the reality check behind the boasting. Standard offerings deliver between 98% and 99% purity, with losses on drying below 0.5%. UV absorption maximum falls near 240 nm, which matters for those running quantification down the HPLC. Storage temperature stays at 2-8°C; push this too high and you’ll see oxidation. Most production-grade material comes vacuum-packed, in amber bottles, or heat-sealed bags, with each package marked for lot number, manufacture and expiry date—no excuses for old stock floating through your workflow.
Smart management reduces risk for people and the environment. Secure handling procedures cut down on exposure. Closed weighing stations, efficient fume hoods, and spill kits in arm’s reach matter more than any safety poster on the wall. Workers deserve training, not just signatures on unread documents. Environmental impact stays minimized when waste is contained in labeled barrels, with manifests for every chemical heading to a disposal contractor. On the buying end, selecting suppliers with clear COA’s (Certificate of Analysis) keeps purchasing clean and legal. Labs, whether industrial or academic, need regular stocktakes so no expired or mixed-up containers get hidden behind fresh deliveries. Public databases can track which country enforces which restrictions, helping international shippers and buyers prevent illegal imports and exports. It’s not enough to meet minimum rules—responsibility means thinking about what gets left behind, who’s exposed, and what kind of example gets set for the next round of chemists, researchers, and quality controllers.
