Pivaloyl chloride is a colorless to pale yellow transparent liquid with a strong pungent and lachrymatory odor. As a highly reactive acylating agent, it contains an acyl chloride (-COCl) functional group and exhibits large steric hindrance. It decomposes violently upon contact with water, releasing hydrogen chloride (HCl) gas.

1. Pharmaceutical intermediates:Used in the synthesis of semi-synthetic antibiotics and pharmaceuticals such as amoxicillin, cephalexin, cephazolin, and dipivefrin.

2. Pesticide intermediates:Key raw material for the production of the insecticide triazamate and the herbicide isoxaflutole.

3. Organic synthesis:Used as a selective acylating agent and amino protecting group for the synthesis of amides, phenolic esters, tert-butyl peroxypivalate, etc.

4. Photosensitive materials:Used as an intermediate for yellow couplers in photographic organic chemicals.
