Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-Bromo-1,3-benzenediamine (CAS 33786-90-2), a certified reference material (molecular formula C6H7BrN2, MW 187.04 g/mol) for analytical method development and quality control.
Owing to a nitrile group, bromine substitution, an aromatic ring system, 5-Bromo-1,3-benzenediamine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 187.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 5-Bromo-1,3-benzenediamine 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.
