1-(2-Methoxy-4-nitrophenyl)-3-methyl-1H-1,2,4-triazole CAS 1185019-82-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Methoxy-4-nitrophenyl)-3-methyl-1H-1,2,4-triazole.

CATO supplies 1-(2-Methoxy-4-nitrophenyl)-3-methyl-1H-1,2,4-triazole (CAS 1185019-82-2), a certified reference material (molecular formula C10H10N4O3, MW 234.21 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-(2-Methoxy-4-nitrophenyl)-3-methyl-1H-1,2,4-triazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
