Description
CATO manufactures 3-Bromo-4-trifluoromethoxybenzenethiol 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.
3-Bromo-4-trifluoromethoxybenzenethiol (CAS 1208076-75-8) is a high-purity analytical reference standard with the molecular formula C7H4BrF3OS and a molecular weight of 273.07 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 3-Bromo-4-trifluoromethoxybenzenethiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
