Methyl 3-cyclopropyl-1-(4-fluorophenyl)-6-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylate CAS 1011397-19-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 387.41 g/mol gives Methyl 3-cyclopropyl-1-(4-fluorophenyl)-6-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methyl 3-cyclopropyl-1-(4-fluorophenyl)-6-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylate (CAS 1011397-19-5), a certified reference material (molecular formula C23H18FN3O2, MW 387.41 g/mol) for analytical method development and quality control.

Methyl 3-cyclopropyl-1-(4-fluorophenyl)-6-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylate (C23H18FN3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
