Chemical Structure
Description
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.
CATO supplies (3,5-Dibromo-1H-1,2,4-triazol-1-yl)(thiophen-2-yl)methanone (CAS 320424-35-9), a certified reference material (molecular formula C7H3Br2N3OS, MW 336.99 g/mol) for analytical method development and quality control.
Structurally, (3,5-Dibromo-1H-1,2,4-triazol-1-yl)(thiophen-2-yl)methanone (C7H3Br2N3OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 336.99 g/mol, it falls into the moderately-high-molecular-weight range. 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.
