Chemical Structure
Description
As a certified reference material (CRM), 2-Chloro-6-methylphenoxyacetic 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.
CATO supplies 2-Chloro-6-methylphenoxyacetic acid (CAS 19094-75-8), a certified reference material (molecular formula C9H9ClO3, MW 200.62 g/mol) for analytical method development and quality control.
2-Chloro-6-methylphenoxyacetic acid (C9H9ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, 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 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.
