Description

Allyl Mercaptan CAS NO 870-23-5 is a highly reactive organosulfur compound characterized by its distinctive, pungent odor. This versatile chemical intermediate is valued for its ability to introduce the allylthio functional group into target molecules, enabling the synthesis of a wide range of specialty chemicals. It is an essential raw material for manufacturers in the agrochemical, pharmaceutical, and polymer industries seeking to develop advanced formulations and materials.

Application

• Agrochemical Synthesis: A key intermediate in the production of pesticides, herbicides, and fungicides, where it acts as a building block for sulfur-containing active ingredients.
• Pharmaceutical Intermediates: Used in the synthesis of drug candidates and active pharmaceutical ingredients (APIs), particularly those requiring thioether or allyl sulfide linkages.
• Polymer Modification: Serves as a chain transfer agent or a reactive monomer in polymerization processes to modify polymer properties and introduce sulfur functionality.
• Flavor and Fragrance Industry: Employed as a precursor for synthesizing sulfur-containing aroma compounds, contributing to garlic-like or meaty notes in complex flavor profiles.
• Chemical Research & Development: A valuable reagent in organic synthesis for constructing complex molecular architectures in academic and industrial R&D laboratories.
• Rubber and Vulcanization Chemistry: Acts as a vulcanization accelerator or a modifying agent in the production of specialty elastomers.

Quality Control

Our Allyl Mercaptan is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) and keep the container tightly sealed when not in use. Keep away from strong oxidizing agents.
