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-(3,5-Dibromo-4-hydroxyphenoxy)acetic acid (CAS 13012-94-7), molecular formula C8H6Br2O4 and molecular weight 325.94 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3,5-Dibromo-4-hydroxyphenoxy)acetic acid (C8H6Br2O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
