Cl3CCHO
Cl3CCHO, also known as chloral or 2,2,2-trichloroacetaldehyde, is an organochlorine aldehyde with the formula C2HCl3O. Its structure comprises a trichloromethyl group (CCl3) attached to an aldehyde carbon (CHO). The compound is a dense, colorless to pale yellow liquid that is highly reactive and a strong lachrymator.
Preparation and occurrence: Chloral is typically produced by the chlorination of acetaldehyde under acidic conditions. It
Properties and reactions: Chloral hydrolyzes in water to form chloral hydrate (trichloroacetaldehyde hydrate): CCl3CHO + H2O ⇌ CCl3CH(OH)2.
Applications: Historically, chloral is the precursor to chloral hydrate, a sedative and hypnotic used in medicine
Safety and handling: Chloral is a potent irritant and lachrymator with toxic effects if inhaled, ingested, or
