Description

Butyl Benzenesulfonate (CAS NO 80-44-4) is a versatile organic sulfonate ester widely utilized as a key intermediate and alkylating agent in advanced chemical synthesis. Its primary commercial value lies in its ability to introduce the butylsulfonyl functional group, making it essential for creating specialized polymers, surfactants, and fine chemicals. This product is particularly critical for manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking reliable, high-purity building blocks for their processes.

Application

• Pharmaceutical Intermediate: Serves as a crucial building block in the synthesis of active pharmaceutical ingredients (APIs) and other drug substances.
• Polymer & Resin Modification: Acts as a cross-linking agent or functional monomer to impart specific properties like solubility or thermal stability to specialty polymers.
• Agrochemical Synthesis: Used in the production of herbicides, pesticides, and plant growth regulators as an alkylating or sulfonating agent.
• Surfactant & Detergent Industry: Functions as a precursor for anionic surfactants and emulsifiers in industrial and institutional cleaning formulations.
• Dye & Pigment Manufacturing: Employed in the synthesis of sulfonated dyes and organic pigments to enhance water solubility and color fastness.
• Chemical Research & Development: A valuable reagent in organic synthesis laboratories for introducing sulfonate ester groups in novel compound development.
• Lubricant & Fuel Additive: Used as a precursor for additives that improve the performance characteristics of industrial lubricants and fuels.
