2-(3-Nitro-1H-1,2,4-triazol-1-yl)-1-(thiophen-2-yl)ethan-1-one CAS 339159-20-5

Description

The occurrence of 2-(3-Nitro-1H-1,2,4-triazol-1-yl)-1-(thiophen-2-yl)ethan-1-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(3-Nitro-1H-1,2,4-triazol-1-yl)-1-(thiophen-2-yl)ethan-1-one (CAS 339159-20-5), molecular formula C8H6N4O3S and molecular weight 238.22 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H6N4O3S, 2-(3-Nitro-1H-1,2,4-triazol-1-yl)-1-(thiophen-2-yl)ethan-1-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 238.22 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.
