Crotonyl chloride

Crotonyl chloride is a reactive acyl chloride commonly used as a building block or intermediate in organic synthesis and biochemical reagent preparation. It serves as an important intermediate for the introduction of crotonyl functional groups in small molecules, peptides, and proteins, and is frequently used in studies involving post-translational modifications such as lysine crotonylation. This reagent is well suited for chemical synthesis applications, including acylation reactions and the preparation of crotonylated substrates for epigenetics and chromatin biology research.
