Chemical Structure
Description
The occurrence of 2-Bromo-4-chloro-1-ethenylbenzene is closely related to chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-4-chloro-1-ethenylbenzene (CAS 1507312-72-2), molecular formula C8H6BrCl and molecular weight 217.49 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-4-chloro-1-ethenylbenzene (C8H6BrCl) contains 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 2-Bromo-4-chloro-1-ethenylbenzene 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.
