2-chloro-1-(2-ethyl-5-methyl-2H-1,2,3-triazol-4-yl)ethan-1-one CAS 1909309-84-7

Description

The occurrence of 2-chloro-1-(2-ethyl-5-methyl-2H-1,2,3-triazol-4-yl)ethan-1-one is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-chloro-1-(2-ethyl-5-methyl-2H-1,2,3-triazol-4-yl)ethan-1-one (CAS 1909309-84-7), a certified reference material (molecular formula C7H10ClN3O, MW 187.63 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H10ClN3O, 2-chloro-1-(2-ethyl-5-methyl-2H-1,2,3-triazol-4-yl)ethan-1-one contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 187.63 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
