Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Bromo-4-fluoro-2-vinylbenzene (CAS 828267-47-6), molecular formula C8H6BrF and molecular weight 201.04 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/bromine substitution, an aromatic ring system, 1-Bromo-4-fluoro-2-vinylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 1-Bromo-4-fluoro-2-vinylbenzene 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.
