Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 451.34 g/mol gives 5'-Nitro-[1,1':3',1''-terphenyl]-3,3'',5,5''-tetracarboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5'-Nitro-[1,1':3',1''-terphenyl]-3,3'',5,5''-tetracarboxylic acid (CAS 2235382-00-8), molecular formula C22H13NO10 and molecular weight 451.34 g/mol, is a CATO reference standard with documented purity and traceability.
5'-Nitro-[1,1':3',1''-terphenyl]-3,3'',5,5''-tetracarboxylic acid (C22H13NO10) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
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.
