Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
332909-71-4 2-hydroxy-4-(1H-tetrazol-1-yl)benzoic acid DTXSID30357635 (CAS 332909-71-4), molecular formula C8H6N4O3 and molecular weight 206.16 g/mol, is a CATO reference standard with documented purity and traceability.
332909-71-4 2-hydroxy-4-(1H-tetrazol-1-yl)benzoic acid DTXSID30357635 (C8H6N4O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
