Chemical Structure
Description
1-(4-Bromo-2-(trifluoromethyl)phenyl)thiourea (CAS 208186-71-4), molecular formula C8H6BrF3N2S and molecular weight 299.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(4-Bromo-2-(trifluoromethyl)phenyl)thiourea (C8H6BrF3N2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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 1-(4-Bromo-2-(trifluoromethyl)phenyl)thiourea 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.
