Chemical Structure
Description
CATO supplies 4-(4-Bromophenyl)-2-(5-(p-tolyl)-1H-pyrazol-1-yl)thiazole (CAS 956795-54-3), a certified reference material (molecular formula C19H14BrN3S, MW 396.30 g/mol) for analytical method development and quality control.
The molecular framework of 4-(4-Bromophenyl)-2-(5-(p-tolyl)-1H-pyrazol-1-yl)thiazole (C19H14BrN3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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. 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.
CATO manufactures 4-(4-Bromophenyl)-2-(5-(p-tolyl)-1H-pyrazol-1-yl)thiazole 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.
