1-(P-tolyl)-2-(1H-1,2,4-triazol-1-yl)ethan-1-one CAS 58905-20-7

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.

1-(P-tolyl)-2-(1H-1,2,4-triazol-1-yl)ethan-1-one (CAS 58905-20-7) is a high-purity analytical reference standard with the molecular formula C11H11N3O and a molecular weight of 201.22 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-(P-tolyl)-2-(1H-1,2,4-triazol-1-yl)ethan-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 201.22 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.
