2,2-dimethylbutyryl chloride

2,2-Dimethylbutyryl chloride (CAS 5856-77-9 ) is a reactive acyl chloride used as a building block in organic synthesis and pharmaceutical manufacturing. It introduces the 2,2-dimethylbutanoyl group into target molecules through acylation reactions. This chemical enables the construction of complex intermediates with defined steric profiles. In pharmaceutical synthesis, it acylates amines, alcohols, and other nucleophiles to produce protected intermediates and active pharmaceutical ingredient precursors. The compound is particularly useful where steric bulk at the alpha-carbon is required. Fragrance and flavor chemists use it to prepare ester and amide derivatives with specific branched-chain profiles suited to fine fragrance and aroma formulations. Biotechnology and life sciences researchers employ it in the preparation of prodrugs, enzyme substrates, and biochemical probes. These applications often require controlled lipophilicity and hydrolytic stability as primary design criteria. It also functions as a catalyst precursor component in select organometallic and coordination chemistry applications. The material is supplied as a liquid, typically in reagent or synthesis grade for industrial and laboratory use. It is available in small research quantities through to multi-kilogram lots for process-scale applications. Purity specifications commonly range from 95% to 98%+ depending on the intended synthetic use and specific customer requirements. Contact us for supply of 2,2-dimethylbutyryl chloride Request Quote
