Butyl methanesulfonate (CAS 1912-32-9), often referred to as butyl mesylate, is a key organic compound with specific chemical and physical properties that make it valuable in various industrial and research applications. Understanding these characteristics is essential for chemists, formulators, and procurement specialists looking to effectively utilize or source this important intermediate. As a dedicated manufacturer and supplier of fine chemicals in China, we aim to provide comprehensive information on butyl methanesulfonate to facilitate informed purchasing decisions.

Key Chemical and Physical Properties
Butyl methanesulfonate is characterized by its molecular formula C5H12O3S and a molecular weight of approximately 152.21 g/mol. Available sources indicate a purity of typically 95% or higher. Physically, it is often described as a colorless to pale yellow solid or liquid, depending on ambient temperature and specific purity grades. Its boiling point is reported around 245°C at atmospheric pressure, though estimated values may vary. The refractive index is commonly around 1.5151. Its density is approximately 1.099 g/cm³ at 25°C. These properties highlight its nature as a moderately dense organic ester.

Synthesis Pathways for Butyl Methanesulfonate
The synthesis of butyl methanesulfonate typically involves the esterification of methanesulfonic acid with butanol, or more commonly, the reaction of methanesulfonyl chloride with 1-butanol in the presence of a base. A common laboratory preparation involves reacting 1-butanol with methanesulfonyl chloride, often in a solvent like dichloromethane and with a base such as pyridine to neutralize the generated HCl. The reaction proceeds under controlled temperature conditions, followed by purification steps like column chromatography to isolate the desired butyl methanesulfonate. The efficiency and purity of the synthesized product are highly dependent on the reaction conditions and the quality of the starting materials.
