CAS 108-24-7

Acetic anhydride

Description:

Acetic anhydride, with the CAS number 108-24-7, is a colorless liquid with a pungent, vinegar-like odor. It is an important reagent in organic synthesis, particularly in the acetylation of various compounds, including alcohols, amines, and carboxylic acids. Acetic anhydride is highly reactive, especially with water, forming acetic acid upon hydrolysis. It has a relatively low boiling point and is soluble in organic solvents such as ether and alcohol, but it is not miscible with water. The substance is classified as a flammable liquid and can pose health hazards, including irritation to the skin, eyes, and respiratory system upon exposure. Due to its reactivity, it should be handled with care in a well-ventilated area, using appropriate personal protective equipment. Acetic anhydride is widely used in the production of pharmaceuticals, plastics, and dyes, making it a valuable compound in both industrial and laboratory settings.
