Description

2,4,6-Trimethylnonane-4-Thiol is a branched-chain aliphatic thiol (mercaptan) with the CAS number 80867-38-5. This specialty organosulfur compound is valued for its unique chemical structure, which imparts specific reactivity and volatility characteristics. It serves as a critical intermediate and functional additive in advanced material synthesis, particularly for industries requiring precise sulfur incorporation or odorant properties.

Application

• Chemical Intermediate: A key building block in the synthesis of more complex sulfur-containing compounds, such as ligands for catalysts or specialty polymers.
• Polymer Modification: Used as a chain-transfer agent or cross-linking agent in the production and modification of synthetic rubbers and specialty plastics to alter properties like elasticity and thermal stability.
• Lubricant & Fuel Additive: Functions as an extreme pressure (EP) additive or anti-wear agent in advanced lubricant formulations, and as a sulfur-containing component in fuel additive packages.
• Odorant & Warning Agent: Its highly volatile and potent thiol odor makes it suitable for use as a warning agent in odorless gases like natural gas or propane for leak detection.
• Flavor & Fragrance Industry: Serves as a precursor for synthesizing specific sulfur-based aroma chemicals used in creating complex flavor and fragrance profiles.
• Research & Development: Employed in academic and industrial R&D for studying thiol-ene click chemistry, surface functionalization, and material science applications.

Quality Control

Our production of 2,4,6-Trimethylnonane-4-Thiol adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure consistency and meet precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Recommended storage temperature: 2-8°C (refrigerated) or as specified on the label.
