Cas no 35432-36-1 (2-Methylpropane-1-sulfonyl Chloride)
2-Methylpropane-1-sulfonyl chloride (isobutylsulfonyl chloride) is a versatile sulfonating reagent widely used in organic synthesis. Its key advantages include high reactivity as a sulfonylating agent, enabling efficient introduction of the sulfonyl group into target molecules. The branched alkyl chain enhances steric control in reactions, improving selectivity in nucleophilic substitutions. It is particularly valuable in pharmaceutical and agrochemical applications for constructing sulfonamides and sulfonate esters. The compound exhibits good stability under standard handling conditions, though it requires moisture-free environments due to its sensitivity to hydrolysis. Its well-defined reactivity profile makes it a reliable choice for precise functionalization in complex synthetic pathways.
