Chemical Structure
Description
3,4-Dibromophenol (CAS 615-56-5) is a high-purity analytical reference standard with the molecular formula C6H4Br2O and a molecular weight of 251.90 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 3,4-Dibromophenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 251.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3,4-Dibromophenol 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.
