6-Phenyl-1-(pyridin-3-ylmethyl)-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid CAS 920627-44-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Phenyl-1-(pyridin-3-ylmethyl)-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid.

6-Phenyl-1-(pyridin-3-ylmethyl)-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid (CAS 920627-44-7), molecular formula C19H14N4O2 and molecular weight 330.34 g/mol, is a CATO reference standard with documented purity and traceability.

6-Phenyl-1-(pyridin-3-ylmethyl)-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid (C19H14N4O2) contains a steroid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
