Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 155.17 g/mol gives 3-(methoxy-d3)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(methoxy-d3)benzoic acid (CAS 96739-37-6) is a high-purity analytical reference standard with the molecular formula C8H5D3O3 and a molecular weight of 155.17 g/mol.
3-(methoxy-d3)benzoic acid (C8H5D3O3) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.
As a certified reference material (CRM), 3-(methoxy-d3)benzoic 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.
