Description

tert-Hexanethiol CAS NO 26544-02-5 is a branched-chain aliphatic thiol characterized by its tertiary carbon structure bonded to the sulfhydryl group. This compound is a versatile chemical intermediate prized for its role as a chain transfer agent in polymer synthesis and as a building block for specialty chemicals. It is essential for manufacturers and R&D facilities in the polymer, agrochemical, and pharmaceutical industries seeking to modify molecular weight or introduce sulfur functionalities.

Application

• Polymer Industry: Primarily used as an effective chain transfer agent (CTA) or modifier in free-radical polymerization processes to control polymer molecular weight and architecture.
• Chemical Synthesis: Serves as a key intermediate for synthesizing other organosulfur compounds, including sulfide ligands, antioxidants, and vulcanization accelerators.
• Agrochemicals: Employed in the production of certain pesticides and fungicides where the tert-butyl moiety imparts specific biological activity or stability.
• Lubricant & Fuel Additives: Acts as a precursor for additives that improve extreme pressure properties, anti-wear performance, and oxidation stability.
• Pharmaceutical Intermediates: Utilized in the research and development of drug candidates, particularly those requiring a lipophilic thiol group.
• Surface Modification: Can be used to create self-assembled monolayers (SAMs) on metal surfaces for corrosion inhibition or to alter surface properties.

Quality Control

Our tert-Hexanethiol is produced under stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets exacting standards for industrial and research applications. A Certificate of Analysis (COA) detailing specific batch results is provided to guarantee supply consistency and traceability.

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, keep container tightly sealed when not in use. Recommended storage temperature is 2-8°C (refrigerated) for extended shelf life, though short-term storage at 15-25°C is acceptable. Keep away from strong oxidizing agents.
