Description
CATO manufactures 6-bromo-3,5-dichloro-1,2-benzoxazole 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.
CATO supplies 6-bromo-3,5-dichloro-1,2-benzoxazole (CAS 1352894-15-5), a certified reference material (molecular formula C7H2BrCl2NO, MW 266.91 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system, 6-bromo-3,5-dichloro-1,2-benzoxazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.91 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
