Description

3-Ethyl-3-Pentanethiol CAS NO 25360-13-8 is a branched-chain tertiary thiol, a versatile sulfur-containing organic compound. Its unique structure makes it a valuable intermediate and functional additive in advanced chemical synthesis. This product is essential for industries requiring specialized sulfur chemistry, such as polymer modification, lubricant formulation, and the synthesis of complex organic molecules.

Application

• Polymer & Rubber Industry: Acts as a chain transfer agent (CTA) or modifier in free-radical polymerization to control molecular weight and polymer architecture.
• Lubricant & Fuel Additives: Serves as an extreme pressure (EP) additive or anti-wear agent due to the sulfur moiety's ability to form protective films on metal surfaces.
• Organic Synthesis Intermediate: Used in the preparation of more complex sulfur-containing compounds, including pharmaceuticals, agrochemicals, and specialty chemicals.
• Flavor & Fragrance Industry: Potential precursor for synthesizing specific sulfur-based aroma compounds, contributing to savory or roasted notes.
• Chemical Research & Development: Employed as a model compound or reagent in studies involving thiol-ene click chemistry and other sulfur-mediated reactions.
• Surface Modification Agent: Can be used to create self-assembled monolayers (SAMs) on metal surfaces for corrosion inhibition or to alter surface properties.

Quality Control

Our 3-Ethyl-3-Pentanethiol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
