Isobutyryl Chloride (79-30-1)

Isobutyryl Chloride is an acid chloride with the chemical formula C4H7ClO and molecular weight 106.55 g/mol. It appears as a colorless to pale yellow liquid with a sharp, pungent odor. It is highly reactive, corrosive, and fumes in moist air. It reacts violently with water, releasing hydrogen chloride.
In terms of uses and applications, Isobutyryl Chloride is widely used as an acylating agent in organic synthesis. It is important in the manufacture of pharmaceuticals, agrochemicals, dyes, and specialty chemicals. It is used to introduce the isobutyryl group into alcohols, amines, and aromatic compounds to form esters and amides. In laboratories, it serves in fine chemical synthesis and intermediate preparation. Additionally, it is applied in polymer and fragrance chemistry where selective acylation reactions are required.
