CAS 694-28-0: 2-Chlorocyclopentanone

Description: 2-Chlorocyclopentanone is a cyclic ketone characterized by the presence of a chlorine atom attached to the second carbon of a cyclopentanone ring. Its molecular formula is C5H7ClO, and it features a five-membered carbon ring with a carbonyl group (C=O) that contributes to its ketone classification. The chlorine substituent introduces unique reactivity, making it useful in various organic synthesis applications. This compound typically appears as a colorless to pale yellow liquid with a distinctive odor. It is moderately soluble in water and more soluble in organic solvents, reflecting its polar carbonyl group and nonpolar cycloalkane structure. 2-Chlorocyclopentanone can undergo nucleophilic substitution reactions due to the presence of the chlorine atom, and it can also participate in various chemical transformations, including reduction and oxidation. Safety precautions should be taken when handling this compound, as it may pose health risks if inhaled or ingested, and appropriate protective equipment should be used.
