Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(3-Chloro-5-methylphenoxy)acetic acid (CAS 25141-36-0), molecular formula C9H9ClO3 and molecular weight 200.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3-Chloro-5-methylphenoxy)acetic acid (C9H9ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-(3-Chloro-5-methylphenoxy)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.
