CAS 5538-51-2

Acetylsalicyloyl chloride

Description:

Acetylsalicyloyl chloride, with the CAS number 5538-51-2, is an acyl chloride derivative of acetylsalicylic acid, commonly known as aspirin. This compound is characterized by its reactivity due to the presence of the acyl chloride functional group, which makes it a potent electrophile. It typically appears as a colorless to pale yellow liquid and has a pungent odor. Acetylsalicyloyl chloride is soluble in organic solvents such as dichloromethane and ether but is generally insoluble in water due to its hydrophobic nature. It is primarily used in organic synthesis, particularly in the preparation of various acetylated compounds and as a reagent in peptide synthesis. The compound can react vigorously with water, alcohols, and amines, releasing hydrochloric acid and forming corresponding acylated products. Safety precautions are essential when handling this substance, as it can cause severe irritation to the skin, eyes, and respiratory tract. Proper storage in a cool, dry place away from moisture is recommended to maintain its stability.
