Description

2-Methyl-2-Butanethiol CAS NO 1679-09-0 is a branched-chain tertiary thiol characterized by its distinctive, powerful odor. This compound is a valuable intermediate and additive in various chemical synthesis and industrial processes due to its reactive thiol group. It is primarily utilized in the production of specialty chemicals, as a flavor and fragrance component, and in the polymer industry for applications such as chain transfer agents and cross-linking modifiers.

Application

• Flavor and Fragrance Industry: Used as a key ingredient or intermediate in the creation of savory, meaty, or sulfurous flavor notes for food products and aroma chemicals.
• Polymer and Rubber Manufacturing: Serves as a chain transfer agent (CTA) in radical polymerizations to control molecular weight and as a cross-linking or modification agent for synthetic rubbers.
• Organic Synthesis: Acts as a versatile building block and sulfur source for synthesizing more complex organosulfur compounds, including pharmaceuticals and agrochemicals.
• Gas Odorant: Employed as an additive to odorize natural gas, propane, or other fuel gases for leak detection due to its low odor threshold and highly recognizable smell.
• Lubricant and Fuel Additives: Utilized in the formulation of extreme pressure (EP) additives and antioxidants for lubricants and fuels.
• Chemical Research & Development: Used in laboratories as a reagent for studying thiol chemistry, catalysis, and material science.

Quality Control

Our 2-Methyl-2-Butanethiol is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with each shipment.

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 when not in use to prevent evaporation and minimize odor release. Store separately from strong oxidizing agents.
