Chemical Structure
Description
2,4-Dibromo-3,5-dichlorophenyl isothiocyanate (CAS 1000574-41-3) is a high-purity analytical reference standard with the molecular formula C7HBr2Cl2NS and a molecular weight of 361.87 g/mol.
2,4-Dibromo-3,5-dichlorophenyl isothiocyanate (C7HBr2Cl2NS) contains a nitrile group, sulfur-containing functionality, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,4-Dibromo-3,5-dichlorophenyl isothiocyanate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
