Description

Ethanethiol CAS NO 6982-46-3 is a volatile organosulfur compound, also known as ethyl mercaptan. It is a critical chemical intermediate and odorant, valued for its extremely low odor detection threshold and distinctive, powerful smell. This makes it essential for safety and process control in industries such as natural gas, petrochemicals, and specialty chemical synthesis.

Application

• Odorant for Fuel Gases: Primary application as a stenching agent for odorless natural gas (LNG, LPG) and propane to enable leak detection for safety.
• Chemical Synthesis Intermediate: Used in the production of pesticides, insecticides, and various sulfur-containing organic compounds.
• Polymer Industry: Serves as a chain transfer agent or modifier in certain polymerization processes.
• Catalyst and Reagent: Employed in organic synthesis and as a catalyst in specific chemical reactions.
• Analytical Chemistry: Utilized as a derivatization agent or standard in gas chromatography and other analytical methods.
• Foulant in Petrochemicals: Monitored as a trace contaminant in refinery feedstocks and natural gas streams.

Quality Control

Our Ethanethiol is manufactured and handled under strict quality protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive quality assurance, with Certificates of Analysis (COA) available for every shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality system is designed to meet the stringent requirements of industrial and specialty chemical applications.

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) when in partially filled containers. Keep away from strong oxidizing agents and bases. Recommended storage temperature: 2-8°C (refrigerated) for optimal stability.
