Chemical Structure
Description
1-bromo-4-(isothiocyanatomethyl)benzene (CAS 155863-32-4), molecular formula C8H6BrNS and molecular weight 228.11 g/mol, is a CATO reference standard with documented purity and traceability.
1-bromo-4-(isothiocyanatomethyl)benzene (C8H6BrNS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 1-bromo-4-(isothiocyanatomethyl)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.
