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-1-isothiocyanatobenzene.
CATO supplies 4-Bromo-2-chloro-1-isothiocyanatobenzene (CAS 98041-69-1), a certified reference material (molecular formula C7H3BrClNS, MW 248.53 g/mol) for analytical method development and quality control.
4-Bromo-2-chloro-1-isothiocyanatobenzene (C7H3BrClNS) 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.
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 4-Bromo-2-chloro-1-isothiocyanatobenzene 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.
