Benzoyl chloride is a chemical compound commonly used in the production of dyes and pharmaceuticals. The spelling of "benzoyl chloride" follows the conventions of English spelling, with a silent "z" and a "y" used to represent the sounds /bɛnˈzɔɪl/ in IPA phonetic transcription. The "o" and "y" represent the diphthong /ɔɪ/, while the "cl" represents the consonant blend /kl/. The phonetic transcription makes it easy to understand the pronunciation of the word and aids in clear communication.
Benzoyl chloride is a chemical compound with the molecular formula C7H5ClO. It is an aromatic organic compound that belongs to the class of acyl chlorides. Benzoyl chloride is a colorless to pale yellow oily liquid with a pungent, irritating odor.
This compound is primarily used in the synthesis of various organic compounds. It is a versatile reagent and an important building block in the production of pharmaceuticals, fragrances, dyes, and polymers. Benzoyl chloride is frequently used in the production of benzoyl peroxide, a common ingredient in acne medications and hair bleach formulations.
The reactivity of benzoyl chloride arises from its acyl chloride nature. It reacts readily with numerous nucleophilic compounds, including alcohols and amines, to form esters and amides, respectively. These reactions are commonly employed in organic synthesis to form a wide range of compounds.
Benzoyl chloride poses certain risks and precautions must be taken while handling it. It is corrosive to skin and eyes, and exposure can cause severe burns, respiratory irritation, and other harmful effects. Therefore, it is essential to use appropriate protective measures, such as wearing gloves and goggles, when working with benzoyl chloride. Additionally, it should be stored in a cool, dry place away from sources of ignition or incompatible substances.

The word "benzoyl" comes from the compound benzoin, which was originally derived from the resin of the benzoin tree. "Benzoin" is derived from the Arabic word "lubān jāwī" (لبان جاوي), meaning "frankincense of Java". The term "benzoyl chloride" refers to the substitution of a hydroxyl group (-OH) in benzoin with a chlorine atom (-Cl). The "chloride" part of the name indicates the presence of the chlorine atom.
