Chemical Structure
Description
The occurrence of 2,5-Dibromophenyl Isothiocyanate is closely related to a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,5-Dibromophenyl Isothiocyanate (CAS 98041-67-9) is a high-purity analytical reference standard with the molecular formula C7H3Br2NS and a molecular weight of 292.98 g/mol.
Based on its molecular formula C7H3Br2NS, 2,5-Dibromophenyl Isothiocyanate contains a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 292.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 2,5-Dibromophenyl Isothiocyanate 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.
