Chloral hydrate is an important organic synthetic raw material and pharmaceutical intermediate widely used in fine chemical industry, pharmaceutical synthesis, pesticide production and laboratory analytical reagents. It can undergo condensation, elimination and substitution reactions to synthesize trichloroacetaldehyde derivatives, herbicides, insecticides and organic pesticide intermediates. In pharmaceutical field, it is used as a raw material for preparing sedative, hypnotic and anticonvulsant drugs, and also applied in the synthesis of multiple pharmaceutical molecular skeletons. In laboratory research, it serves as a common analytical reagent, preservative and biological fixative, widely used in microbial preservation and histological specimen preparation. Meanwhile, it is an essential building block for the synthesis of resin additives, plastic modifiers and daily chemical raw materials, playing an irreplaceable role in downstream fine chemical product development and process optimization.

Chloral hydrate is irritating and has certain systemic toxicity with multiple health hazards to human body. Inhalation of its vapor or dust can irritate respiratory tract, causing cough, sore throat, dizziness and headache. Skin contact may lead to redness, burning sensation and allergic irritation; long-term contact may cause skin dryness and damage. Eye contact will result in severe irritation, conjunctival congestion and pain, requiring immediate rinsing with plenty of water. Accidental ingestion may cause nausea, vomiting, abdominal pain, central nervous system inhibition and even affect heart and liver functions. All operations should be carried out in a well-ventilated fume hood with protective gloves, goggles and dust mask. Store tightly sealed in cool dry place, away from heat, strong alkalis and oxidants. Waste materials and contaminated packaging must be treated as hazardous waste to prevent environmental pollution and accidental poisoning risks.
