Dichloroacetic acid ultrapure is a high-purity organic acid (CAS 79-43-6, Cl₂CHCOOH) primarily used in biochemical research, pharmaceutical synthesis, and analytical applications where impurity-free reagents are critical. Documented applications include serving as an intermediate in the synthesis of chloramphenicol and allantoin, as a test reagent in fiber analysis, and as a disinfectant or biocide. It is a regulated, hazardous substance requiring careful handling. This ultrapure grade offers ≥99.9% purity with minimal trace contaminants, ideal for sensitive assays. Store between 2–8°C in a tightly sealed container under inert gas to prevent degradation. The signal word is Danger, indicating severe hazards (corrosive, toxic in contact with skin). Full SDS and COAs are provided upon request. Molekula supplies Dichloroacetic acid Ultrapure from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
