Chemical Structure
Description
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.
4-Bromo-1-(methylthio)-2-(trifluoromethyl)-benzene (CAS 300356-31-4) is a high-purity analytical reference standard with the molecular formula C8H6BrF3S and a molecular weight of 271.10 g/mol.
Owing to sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system, 4-Bromo-1-(methylthio)-2-(trifluoromethyl)-benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 4-Bromo-1-(methylthio)-2-(trifluoromethyl)-benzene 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.
