Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-2-chloro-6-fluorophenylisothiocyanate.
4-Bromo-2-chloro-6-fluorophenylisothiocyanate (CAS 1000572-98-4) is a high-purity analytical reference standard with the molecular formula C7H2BrClFNS and a molecular weight of 266.52 g/mol.
4-Bromo-2-chloro-6-fluorophenylisothiocyanate (C7H2BrClFNS) contains a nitrile group, sulfur-containing functionality, fluorine/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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
