2-Acetyl Thiophene draws a lot of attention within chemical circles and industrial sectors, especially for those who work with heterocyclic compounds. It comes from the thiophene family, a group known for their sulfur-containing rings. In everyday use, 2-Acetyl Thiophene usually appears as a solid or crystalline powder, and its structure gives it a distinctive earthy, nutty scent. As a specialty raw material, it finds its way into fine chemical synthesis and adds strength to the aromatic profiles of flavors and fragrances. This compound, with the formula C6H6OS, holds value far beyond its pungent aroma.
Every interaction with 2-Acetyl Thiophene reveals something about its behavior. The typical material ranges from pale yellow to off-white crystals, showing clarity and consistency when in purified form. Its molecular weight lands at 126.18 g/mol, making it manageable for various direct chemical reactions and easier to track during analysis. The melting point sits between 29 and 33°C, just low enough for the solid to soften in your hand or under slight exposure to environmental heat. Those handling bulk quantities notice it becomes liquid above room temperature, and it quickly reforms to a solid once cooled or stored under standard conditions. Density clocks in at 1.153 g/cm³, so it feels neither especially light nor cumbersome; these physical properties come into play when calculating dosing for chemical synthesis, ensuring consistency in product outcomes and minimizing waste.
Looking closer at the structure, 2-Acetyl Thiophene includes a thiophene ring—a five-membered ring with one sulfur atom—bonded to an acetyl group at the 2-position. Its structure influences both the reactivity and the unique scent profile noticed in many end-use products. Compared with other substituted thiophenes, this arrangement increases the compound’s nucleophilicity, which matters in reactions like Friedel-Crafts acylations and as a building block for pharmaceutical intermediates. The molecular formula, C6H6OS, confirms these features, and any experienced chemist reading a mass spectrometry printout or FTIR spectrum recognizes the importance of having every atom in the right place for these compounds to perform as expected.
Solubility matters most during mixing and purification. 2-Acetyl Thiophene shows moderate solubility in most polar organic solvents, such as ethanol, ether, and acetone. Water generally doesn’t dissolve it well, so sticky spills need prompt cleaning to avoid crystallization on hard surfaces. Producers often offer this chemical as solid flakes, crystalline powder, or even as a solution in ethanol or acetone, shipped in barrels or sealed glass bottles. In large-scale distribution, drums or specialized containers minimize contamination and moisture absorption. Raw materials supplied in this fashion support high-throughput manufacturing needs and are ready for precise dosing.
Trade and regulation sway the market for 2-Acetyl Thiophene, just as they do with many specialty chemicals. Under international shipping and customs law, the HS Code for this substance typically falls within 2934.9990, ensuring authorities and logistics teams can properly track and manage cross-border movement. Importers and exporters depend on these codes to avoid misplacement or regulatory trouble at customs. Businesses buying raw materials in bulk reference the HS Code for invoicing, safety data sheet classification, and for establishing environmental compliance in line with specific national standards.
Anyone with a background in chemical production or fragrance development knows that 2-Acetyl Thiophene carves out a niche role. This compound often acts as a key raw material for synthesizing advanced intermediates, especially in the pharmaceutical and agrochemical industries, thanks to its reactive acetyl group and aromatic sulfur core. In the world of flavors and fragrances, 2-Acetyl Thiophene brings roasted, nutty notes that subtly enhance tobacco and gourmet blends or impart natural characteristics in baked snack aromas. Paint, resin, and polymer manufacturers sometimes reach for this material to boost UV resistance or introduce custom features in specialty finishes. The consistency, reliability, and purity of raw 2-Acetyl Thiophene shape the final quality of these downstream products.
Working on the laboratory bench or loading packaging lines brings safety into sharp focus. 2-Acetyl Thiophene bears a classification as a hazardous chemical, with particular risk to eye and skin contact. The compound can cause irritation upon direct contact and inhalation of dust or vapor may discomfort the airways. Spill management teams and handlers rely on basic personal protective equipment: gloves, goggles, lab coats, and, where ventilation runs poor, respirators. Though not flagged as acutely toxic or carcinogenic, prudent storage and careful handling go a long way towards keeping incidents at zero. Strong oxidizing agents might trigger unwanted reactions, so separation during transit and storage sits high on the priority list. Reference to relevant GHS (Globally Harmonized System) safety data ensures users comply with international and local law, protecting both themselves and the environment from downstream contamination.
Manufacturers sourcing 2-Acetyl Thiophene as a raw material see the whole chain, from mining sulfur precursors through to purification and waste management. Environmental compliance now gets more attention than ever. Processing facilities implement air scrubbing and solvent recovery, and every reputable supplier posts disposal guidelines to help downstream customers manage chemical waste. Local regulations in Europe and North America impact the way the material enters the market and guide emissions reporting, spill control, and emergency protocols. As a result, end users need to stay current with changes in SAFETY and environmental law, since fines or shutdowns can follow mistaken handling or improper discharge.
No matter how small the individual batch, maintaining strict quality standards around 2-Acetyl Thiophene benefits both industry and consumer. Specification sheets from reputable vendors include batch numbers, analytical data, and guarantee product purity, all of which feed into quality management and regulatory audit trails. Buyers—whether from flavor houses, chemical plants, or R&D labs—invest in training their teams, not just because industry standards require it, but because safe, informed handling directly supports reliable production and protects staff health. The call for greener chemistry and lower emissions will continue to impact best practices, as industry leaders look for balance between cutting-edge product development and environmental stewardship.
