Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 2,6-Dibromo-3,4-dichlorophenyl isothiocyanate (CAS 22228-95-1), a certified reference material (molecular formula C7HBr2Cl2NS, MW 361.87 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system, 2,6-Dibromo-3,4-dichlorophenyl isothiocyanate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 361.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
