2-Acetylpyrrole, also known by the IUPAC name 1-(1H-pyrrol-2-yl)ethan-1-one, turns up in several chemical industries thanks to its distinct aromatic features and handy reactivity. Whether in solid or liquid form, its pale white color often hints at its purity. Folks order it under the HS Code 29333990, and anyone dealing with food flavor chemistry will stumble across this molecule. Its chemical formula — C6H7NO — raises curiosity due to its structure: a pyrrole ring married to an acetyl group at the 2-position, which makes it carry that familiar roasted, nutty scent you get from baked or cooked foods.
2-Acetylpyrrole usually shows up as a crystalline solid, sometimes presenting as a powder, flakes, or even pearls depending on the manufacturer’s process or storage. Density checks reveal values close to 1.128 g/cm³, and you’ll see sublimation rather than melting in some storage conditions due to its aromatic ring. This compound dissolves well in organic solvents like ethanol, ether, and chloroform, allowing quick and flexible use in both lab settings and industrial applications. Avoiding moisture and direct sunlight keeps the molecular structure in shape, minimizing decomposition. Bulk material often gets packed in amber glass or plastic, showing respect for its sensitivity to light and air. Its melting point hangs around 59–62 °C, and weighing it with care proves important because some folks have slight allergic skin reactions.
This molecule sports a five-membered pyrrole ring with a carbonyl group sitting where it can interact, opening doors for more chemical modifications. Whether synthesizing active pharmaceutical ingredients, adding distinct flavor to roasted nuts, or making advanced materials for research, 2-Acetylpyrrole delivers versatility. Its odor profile shines in snack food and beverage flavoring, giving both professionals and home cooks that signature note found in popcorn or roasted coffee. Some labs use it as a starting material to produce specialty pyrrole derivatives, essential for organic electroluminescence and dye chemistry. This chemical moves beyond the bench and becomes present in the nitty-gritty of flavor and fragrance, thanks to its reactivity and sensory attributes.
Product shipments provide 2-Acetylpyrrole typically at 98% or higher purity, with trace impurities determined via HPLC or GC as outlined by the seller’s certificate of analysis. The CAS number, 1072-83-9, brings precision; for ordering and inventory, this cross-links efficiently with hazard review documents. Shipping drums, bottles, or bags carry markings for gross and net weights, and retaining the original packaging prevents cross-contamination or accidental spillage. Its specific gravity ensures proper dosing in liquid formulations, and strict storage at or below room temperature avoids unwanted oxidation. Tests for melting behavior, water solubility, and stability under UV light guide purchasing staff who want quality assurance down to the last granule.
Working with 2-Acetylpyrrole means paying close attention to the Material Safety Data Sheet (MSDS). Its solid form can trigger allergic responses in sensitive skin, and inhalation of powdered material poses risks for those with respiratory conditions. Most chemical supply catalogs score it with hazard statements: irritant and harmful in high concentrations. Wearing goggles, gloves, and working in well-ventilated spaces helps avoid unnecessary trouble. If spilled, the solid or powder needs quick sweeping and disposal in labeled hazardous waste containers. Direct ingestion produces nausea and headache in some cases, so keeping food and drink out of the lab stands as a basic rule. Under heat or flame, this material breaks down, releasing nitrogen and carbon oxides, calling for proper fire safety protocols and careful storage away from oxidizing agents. Disposal as hazardous chemical waste adheres to local regulations.
Reliable sourcing starts with vetting chemical suppliers whose batches carry full documentation and traceable lot numbers. World supply chains influence costs for 2-Acetylpyrrole, since key raw materials such as acetic anhydride and pyrrole come from complex upstream chemical processes. Quality checks on raw stocks impact the end material’s consistency in both flavor and lab synthesis. As demand rises for advanced flavors and specialty chemicals, volume buyers typically secure annual contracts, while small-batch users rely on fine chemical markets. Keeping the product safe and compliant with global shipping rules ensures it reaches everyone from food companies to pharmaceutical labs with little delay or regulatory holdup.
Manufacturers and scientists keep pushing the boundaries of 2-Acetylpyrrole, not just in flavoring but also as a stepping stone for new organic compounds. Its sensory impact on roasted foods makes it indispensable in snack product design, and synthetic chemists harvest its reactive positions for advanced molecule construction. As research on sustainable chemical processes grows, more companies emphasize greener sourcing and tighter waste controls, reducing risk for workers and the environment alike. In daily work with chemicals like 2-Acetylpyrrole, clear communication, proper training, and respect for the substance’s quirks keep production safe, prompt, and innovative.
