Chemical Structure
Description
METHYL 2-CHLORO-2-(2-CHLOROPHENYL)ACETATE (CAS 90055-47-3), molecular formula C9H8Cl2O2 and molecular weight 219.06 g/mol, is a CATO reference standard with documented purity and traceability.
METHYL 2-CHLORO-2-(2-CHLOROPHENYL)ACETATE (C9H8Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures METHYL 2-CHLORO-2-(2-CHLOROPHENYL)ACETATE under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
