Product Description

Product Introduction

Isobutyryl chloride (CAS 79-30-1),  also known as 2-methylpropanoyl chloride, is a branched acid chloride

It is a highly reactive compound that can undergo acylation reactions with alcohols, amines, thiols, etc., to introduce an isobutyryl group

Due to its extremely high hydrolytic activity, it readily produces hydrochloric acid (HCl) and corresponding acids in air or humid environments; therefore, strict dryness must be maintained during its synthesis

 

Applications & Descriptions

  1. Organic Synthesis Reagent
    Used to introduce isobutyryl groups into amines, alcohols, or phenols to generate isobutyramides, isobutyryl esters, etc.

  2. Intermediate for Peroxide & Polymer Chemistry
    Used as an intermediate in organic peroxide and polymer chemistry, particularly for the synthesis of certain organic peroxide acids or crosslinking agents

  3. Pharmaceutical / Fine Chemical Building Block
    Used for the synthesis of pharmaceutical intermediates and fine chemicals, such as constructing branched acyl structures

  4. Acylating Agent in Small-Scale Lab
    Used in the laboratory as an acylation reagent for reaction mechanism studies or derivatization tests

  5. Specialty Material / Functional Molecules
    Used to synthesize functionalized molecules containing isobutyryl groups (such as functional monomers, fragrance intermediates, etc.) or as a protecting group
