Chemical Structure
Description
CATO manufactures 4-(1-ethyl-1H-1,2,3-triazol-4-yl)phenol hydrobromide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
4-(1-ethyl-1H-1,2,3-triazol-4-yl)phenol hydrobromide (CAS 1798683-30-3) is a high-purity analytical reference standard with the molecular formula C10H11N3OHBr and a molecular weight of 270.13 g/mol.
The molecular framework of 4-(1-ethyl-1H-1,2,3-triazol-4-yl)phenol hydrobromide (C10H11N3OHBr) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
