Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 156.17 g/mol gives 3-Methoxybenzoic acid-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Methoxybenzoic acid-d4 (CAS 2098655-87-7), molecular formula C8H4D4O3 and molecular weight 156.17 g/mol, is a CATO reference standard with documented purity and traceability.
3-Methoxybenzoic acid-d4 (C8H4D4O3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
