2-Methyl-3(5Or6)-Furfurylthio Pyrazine stands out in the world of flavor and fragrance chemistry. It comes from the pyrazine family, known for deep roasted, nutty, or earthy notes. Used in flavors for snacks, coffee, and sometimes perfumes, this compound serves as a subtle building block, helping to round out a formula with warm, comforting qualities. Many food scientists recognize it for its ability to deepen and improve authentic taste profiles, especially where natural roasting and browning generate these types of molecules. Still, just rattling off its applications doesn’t mean much unless you’ve handled the material, measured it at the bench, and seen how these molecules behave.
Working with 2-Methyl-3(5Or6)-Furfurylthio Pyrazine, you realize how small amounts go a long way. Confectionery and savory snack formulators rely on its power, often blending it with other pyrazines or sulfur-containing compounds. In technical settings, it sometimes acts as a marker for thermal processing or as a focus for new flavor systems. Certain regulatory landscapes demand close attention to purity and traceability. For industrial buyers or R&D teams selecting raw materials, consistency in physical form—flakes, powder, pearls—can change how you store, handle, and meter out these chemicals in production environments.
At the molecular level, this compound holds the formula C10H10N2OS, creating a backbone of pyrazine fused with thio (sulfur) and methyl groups. Its structure brings about those roast and crust-like characteristics that show up in cooked foods. The positioning of furfurylthio and methyl groups influences aroma and volatility, separating it from other pyrazines. In the lab, one glance at the structure diagram hints at its strong affinity for interaction with Maillard reaction intermediates, connecting it to the chemistry of browned crust and caramelization. Molecular weight clocks in at about 206.27 g/mol, so analytical teams can spot it easily with standard mass spectrometry, which streamlines quality checks.
As a raw material, you might see it supplied as a pale yellow to brown solid, often as flakes or crystalline powder, sometimes compacted into pearls for industrial use. Density comes in close to 1.19 g/cm³ at standard temperature and pressure, putting it in the typical range for heavier organic flavor ingredients. It shows limited solubility in water—which isn’t surprising for a molecule designed for oil-based application systems—and dissolves better in alcohols and glycols. Users working at scale rely on specs like melting point (sitting between 68-74°C) to guide handling and incorporation steps. Analytical specs should always note purity and trace contaminants, especially since these sulfur-containing compounds can be potent at very low levels.
Handling chemicals like 2-Methyl-3(5Or6)-Furfurylthio Pyrazine always calls for thoughtful risk management. Suppliers assign it a hazardous material status, based on possible skin and respiratory irritation and the general rules for synthetic pyrazines and thioethers. Users should check the safety data sheet (SDS) for proper ventilation and personal protection, plus chemical spill response. Disposal follows local chemical waste protocols. Once, while readying a sample for evaluation, I caught a whiff that lingered; it reminded me that even seemingly benign aromatic compounds can trigger sensitivities — always worth the gloves and fume hood. In liquid and solid forms, storage in cool, dry, tightly-closed containers keeps product performance reliable and safety risks lower. Never underestimate the importance of clear labeling, especially given potential confusion between similar aromatic compounds in a busy lab or flavor house.
Shipments of 2-Methyl-3(5Or6)-Furfurylthio Pyrazine move under the Harmonized System (HS) Code—most often 2933.19 for pyrazine derivatives. Importers and exporters use this code to declare goods, manage tariffs, and satisfy customs authorities worldwide. Details like CAS number (often 94209-19-3) and EC number pop up in supplier documents and regulatory filings. End-users review specs like color, appearance, and purity before each batch enters production, double-checking any supplier’s claims with internal QC labs. Factoring in all these reference points, buyers can compare options across regions, keep audit trails, and ensure every gram matches regulatory and client requirements.
In sourcing 2-Methyl-3(5Or6)-Furfurylthio Pyrazine, procurement teams look at not just price, but batch reproducibility, traceability, and vendor transparency. Since this specialty chemical has a narrow producer base, I’ve seen teams test multiple lots for off-flavors or unpredictable impurities. Some suppliers specialize in sustainable or traceable options, which can influence purchasing decisions at larger food or fragrance companies. For formulators who care about non-GMO, allergen risk, and kosher/halal status, comprehensive documentation makes it easier to meet downstream requirements. Quality control teams hammer these points home—one off-note or out-of-spec shipment can spoil hundreds of kilos of finished product.
Hazard and risk always push teams to improve safety across chemical handling processes. Regular staff training, consistent use of gloves, goggles, and masks, and dedicated weighing stations all help. Some production floors install improved fume extraction or set up semi-automated dosing systems to cut down on manual contact. At the development bench, smaller scale dilutions and closed-system containers make a real difference. Digital material tracking and barcoding reduce mix-up errors, especially where multiple similar thiopyrazines operate at once. For companies facing stricter hazard thresholds or customer safety concerns, investing in regular third-party residue analysis and storage monitoring tools can tighten up the quality chain.
