Chemical Structure
Description
3-Methyl-1-phenyl-1H-pyrazolo[4,3-c]quinolin-4(5H)-one (CAS 97789-05-4) is a high-purity analytical reference standard with the molecular formula C17H13N3O and a molecular weight of 275.30 g/mol.
The molecular framework of 3-Methyl-1-phenyl-1H-pyrazolo[4,3-c]quinolin-4(5H)-one (C17H13N3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 3-Methyl-1-phenyl-1H-pyrazolo[4,3-c]quinolin-4(5H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
