2,4-Dibromo-1-isothiocyanatobenzene CAS 13037-63-3 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2,4-Dibromo-1-isothiocyanatobenzene (CAS 13037-63-3) is a high-purity analytical reference standard with the molecular formula C7H3Br2NS and a molecular weight of 292.98 g/mol.

2,4-Dibromo-1-isothiocyanatobenzene (C7H3Br2NS) contains a nitrile group, sulfur-containing functionality, 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).

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.
