For professionals involved in chemical research and manufacturing, a thorough understanding of product specifications and applications is essential. 1-Butyl-3-methylimidazolium chloride (CAS 79917-90-1) is a prominent chemical intermediate, valued for its unique properties and its critical role in several synthetic pathways. This article aims to guide buyers and formulators on what to expect when sourcing this important compound.

Typically, 1-Butyl-3-methylimidazolium chloride is described as a cream to yellow crystalline powder. Key quality parameters that buyers should inquire about include its purity, which is often specified as ≥98.00% or higher, and its water content, usually kept to a maximum of 1.0% or lower. These specifications are crucial, especially when the compound is used in sensitive reactions like Friedel-Crafts alkylation, where impurities can significantly affect reaction efficiency and product quality. The ability to purchase this chemical with confidence in its purity is a primary concern for R&D scientists and production managers.

The primary application for 1-Butyl-3-methylimidazolium chloride is its use in conjunction with AlCl3 for Friedel-Crafts alkylation reactions. This makes it an invaluable reagent for manufacturers looking to synthesize a wide array of organic compounds. Beyond this, its solubility characteristics in various organic solvents also suggest potential uses in other areas of organic synthesis as a solvent or catalyst. When you buy this product, you are investing in a versatile tool for chemical innovation.

To secure a reliable supply, it is recommended that procurement managers contact leading chemical manufacturers and suppliers, particularly those based in China. Obtaining quotes, reviewing detailed Certificates of Analysis (CoA), and understanding packaging options (e.g., 25kg drums) are all part of a robust sourcing strategy for CAS 79917-90-1.
