4-Chlorobenzoyl fluoride

Description:
4-Chlorobenzoyl fluoride, with the CAS number 456-21-3, is an organic compound characterized by the presence of a benzoyl group substituted with a chlorine atom at the para position and a fluoride atom. It is a colorless to pale yellow liquid that is typically used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals. The compound exhibits a moderate level of volatility and is soluble in organic solvents, making it useful in chemical reactions that require a non-aqueous environment. Its reactivity is primarily attributed to the electrophilic nature of the carbonyl group, which can participate in nucleophilic substitution reactions. Additionally, the presence of the chlorine and fluoride substituents can influence the compound's reactivity and stability, making it a valuable building block in organic synthesis. Due to its chemical properties, appropriate safety measures should be taken when handling this substance, as it may pose health risks if inhaled or ingested.
