Chemical Structure
Description
The occurrence of 4-Methoxy-<SUP>13</SUP>C,d<SUB>3</SUB>-benzoic acid is closely related to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Methoxy-<SUP>13</SUP>C,d<SUB>3</SUB>-benzoic acid (CAS 1216592-91-4), molecular formula C7[13C]H11D3O3 and molecular weight 162.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Methoxy-<SUP>13</SUP>C,d<SUB>3</SUB>-benzoic acid (C7[13C]H11D3O3) is characterized by deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage. 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 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 4-Methoxy-<SUP>13</SUP>C,d<SUB>3</SUB>-benzoic acid 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.
