Chemical Structure

1,3-Diphenyl-1H-pyrazolo[4,3-c]quinolin-4(5H)-one CAS 89522-18-9 chemical structure

Description

The occurrence of 1,3-Diphenyl-1H-pyrazolo[4,3-c]quinolin-4(5H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1,3-Diphenyl-1H-pyrazolo[4,3-c]quinolin-4(5H)-one (CAS 89522-18-9), a certified reference material (molecular formula C22H15N3O, MW 337.37 g/mol) for analytical method development and quality control.

1,3-Diphenyl-1H-pyrazolo[4,3-c]quinolin-4(5H)-one (C22H15N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
