Description

3-Methyl-2-Buten-1-Thiol is a highly volatile organosulfur compound with a distinctive, potent aroma. This chemical is a critical flavor and fragrance intermediate, valued for its ability to impart roasted, meaty, or alliaceous notes at extremely low concentrations. It is essential for manufacturers in the flavor and fragrance industry, as well as for researchers in organic synthesis and analytical chemistry developing aroma standards.

Application

• Flavor & Fragrance Industry: A key building block for creating savory, roasted, meat-like, garlic, or onion flavor profiles in processed foods, snacks, and savory formulations.
• Aroma Compound Synthesis: Serves as a crucial intermediate in the synthesis of more complex sulfur-containing aroma molecules used in perfumery and flavorings.
• Food & Beverage Analysis: Used as a certified reference material or standard in gas chromatography (GC) and mass spectrometry (MS) for the accurate identification and quantification of flavor compounds.
• Research & Development: Employed in academic and industrial R&D for studying reaction mechanisms involving thiols and for developing new synthetic methodologies.
• Specialty Chemical Manufacturing: Acts as a precursor in the production of certain agrochemicals, pharmaceuticals, and other fine chemicals where a specific sulfur-containing moiety is required.

Quality Control

Our 3-Methyl-2-Buten-1-Thiol is produced and handled under strict quality management protocols. Each batch is analyzed to ensure high purity and consistency, with specifications typically covering identity, assay, and impurity profiles. Certificates of Analysis (COA) documenting these results are available for every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) at 2-8°C to minimize oxidation and volatility. Keep away from heat, sparks, and open flame. The container should be kept tightly sealed in a cool, well-ventilated place separate from strong oxidizing agents.
