Description
CATO manufactures 3-(Bromomethyl)benzenethiol 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-(Bromomethyl)benzenethiol (CAS 145440-82-0), molecular formula C7H7BrS and molecular weight 203.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, bromine substitution, an aromatic ring system, 3-(Bromomethyl)benzenethiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 203.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
