1-(Propan-2-yl)-6-(thiophen-2-yl)-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid CAS 879576-89-3

Description

The occurrence of 1-(Propan-2-yl)-6-(thiophen-2-yl)-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(Propan-2-yl)-6-(thiophen-2-yl)-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid (CAS 879576-89-3), molecular formula C14H13N3O2S and molecular weight 287.34 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H13N3O2S, 1-(Propan-2-yl)-6-(thiophen-2-yl)-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 287.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
