5-chloro-6-cyclopropyl-1,3-dimethyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid CAS 1018142-01-2

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-chloro-6-cyclopropyl-1,3-dimethyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 265.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 5-chloro-6-cyclopropyl-1,3-dimethyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid (CAS 1018142-01-2), a certified reference material (molecular formula C12H12ClN3O2, MW 265.70 g/mol) for analytical method development and quality control.

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.
