Description

Ethanethiol CAS NO 75-08-1 is a volatile organosulfur compound characterized by its intensely pungent odor. This high-purity chemical intermediate is critical for synthesis and odorization processes where precise reactivity and consistent quality are paramount. It serves as a key building block in the production of agrochemicals, pharmaceuticals, and as an odorant for safety in fuel gases like propane and natural gas. Industrial buyers rely on it for its specific thiol functionality and reliable performance in demanding applications.

Application

• Fuel Gas Odorant: Added in minute quantities to odorless gases like propane, natural gas (LNG/LPG), and butane to provide a detectable warning smell for leaks.
• Agrochemical Synthesis: Serves as a key intermediate and precursor in the manufacture of pesticides, insecticides, and fungicides.
• Pharmaceutical Intermediate: Used in the synthesis of certain active pharmaceutical ingredients (APIs) and other fine chemicals.
• Polymer & Rubber Industry: Acts as a chain transfer agent in polymerization processes and a modifier for synthetic rubber.
• Chemical Synthesis: Employed as a versatile reagent for introducing the ethylthio group into organic molecules.
• Catalyst & Stabilizer: Used in certain catalytic systems and as a stabilizer for chemical formulations.
• Laboratory Research: Utilized as a standard or reagent in analytical chemistry and R&D for sulfur chemistry studies.

Quality Control

Our Ethanethiol is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including Gas Chromatography (GC) for assay and impurity profiling, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements.

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 nature, containers must be kept tightly sealed and upright to prevent leakage and vapor release. Store separately from strong oxidizing agents, strong acids, and strong bases.
