Description
CATO manufactures 1-bromo-4-(chloromethyl)-2-methylbenzene 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.
1-bromo-4-(chloromethyl)-2-methylbenzene (CAS 149104-97-2) is a high-purity analytical reference standard with the molecular formula C8H8BrCl and a molecular weight of 219.51 g/mol.
1-bromo-4-(chloromethyl)-2-methylbenzene (C8H8BrCl) contains chlorine/bromine substitution, an aromatic ring system. 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.
