Chemical Structure
Description
CATO supplies 1-(4-Bromophenyl)-2-(3,5-dibromo-1H-1,2,4-triazol-1-yl)ethan-1-one (CAS 919260-15-4), a certified reference material (molecular formula C10H6Br3N3O, MW 423.89 g/mol) for analytical method development and quality control.
The molecular framework of 1-(4-Bromophenyl)-2-(3,5-dibromo-1H-1,2,4-triazol-1-yl)ethan-1-one (C10H6Br3N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
