Chemical Structure
Description
3-Chloro-4,6-dibromo-2-methylphenyl isothiocyanate (CAS 1000573-77-2) is a high-purity analytical reference standard with the molecular formula C8H4Br2ClNS and a molecular weight of 341.45 g/mol.
3-Chloro-4,6-dibromo-2-methylphenyl isothiocyanate (C8H4Br2ClNS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 3-Chloro-4,6-dibromo-2-methylphenyl isothiocyanate 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.
