Chemical Structure
Description
The occurrence of Dibromo(phenyl)phosphane is closely related to organophosphorus functionality, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dibromo(phenyl)phosphane (CAS 1073-47-8), molecular formula C6H5Br2P and molecular weight 267.89 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, bromine substitution, Dibromo(phenyl)phosphane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.89 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 Dibromo(phenyl)phosphane 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.
