Description

Compared with other compounds in its class, the molecular weight of 358.35 g/mol gives [5-Methyl-1-(4-nitrophenyl)-1H-1,2,3-triazol-4-yl](2-naphthyl)methanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies [5-Methyl-1-(4-nitrophenyl)-1H-1,2,3-triazol-4-yl](2-naphthyl)methanone (CAS 478041-07-5), a certified reference material (molecular formula C20H14N4O3, MW 358.35 g/mol) for analytical method development and quality control.

The molecular framework of [5-Methyl-1-(4-nitrophenyl)-1H-1,2,3-triazol-4-yl](2-naphthyl)methanone (C20H14N4O3) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
