Description
As a certified reference material (CRM), 2-[2-chloro-5-(trifluoromethyl)phenoxy]acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
2-[2-chloro-5-(trifluoromethyl)phenoxy]acetic acid (CAS 861064-49-5), molecular formula C9H6ClF3O3 and molecular weight 254.59 g/mol, is a CATO reference standard with documented purity and traceability.
2-[2-chloro-5-(trifluoromethyl)phenoxy]acetic acid (C9H6ClF3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
