1-(2,6-dichlorophenyl)-5-methyl-1H-1,2,4-triazole-3-carboxylic acid CAS 1154101-06-0

Description

The occurrence of 1-(2,6-dichlorophenyl)-5-methyl-1H-1,2,4-triazole-3-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(2,6-dichlorophenyl)-5-methyl-1H-1,2,4-triazole-3-carboxylic acid (CAS 1154101-06-0) is a high-purity analytical reference standard with the molecular formula C10H7Cl2N3O2 and a molecular weight of 272.09 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(2,6-dichlorophenyl)-5-methyl-1H-1,2,4-triazole-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 272.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
