4-[4-(methoxycarbonyl)-3-methyl-6-phenyl-1h-pyrazolo[3,4-b]pyridin-1-yl]benzoic acid CAS 1011398-75-6

Description

Compared with other compounds in its class, the molecular weight of 387.39 g/mol gives 4-[4-(methoxycarbonyl)-3-methyl-6-phenyl-1h-pyrazolo[3,4-b]pyridin-1-yl]benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-[4-(methoxycarbonyl)-3-methyl-6-phenyl-1h-pyrazolo[3,4-b]pyridin-1-yl]benzoic acid (CAS 1011398-75-6), a certified reference material (molecular formula C22H17N3O4, MW 387.39 g/mol) for analytical method development and quality control.

The molecular framework of 4-[4-(methoxycarbonyl)-3-methyl-6-phenyl-1h-pyrazolo[3,4-b]pyridin-1-yl]benzoic acid (C22H17N3O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
