Methyl 5-(2-methoxy-2-oxoethyl)-1-(4-nitrophenyl)-1H-1,2,3-triazole-4-carboxylate CAS 91306-60-4

Description

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.

CATO supplies Methyl 5-(2-methoxy-2-oxoethyl)-1-(4-nitrophenyl)-1H-1,2,3-triazole-4-carboxylate (CAS 91306-60-4), a certified reference material (molecular formula C13H12N4O6, MW 320.26 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Methyl 5-(2-methoxy-2-oxoethyl)-1-(4-nitrophenyl)-1H-1,2,3-triazole-4-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.26 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).

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.
