Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-Bromobenzyl)triphenylphosphonium chloride.
(3-Bromobenzyl)triphenylphosphonium chloride (CAS 18880-07-4) is a high-purity analytical reference standard with the molecular formula C25H21BrPCl and a molecular weight of 467.77 g/mol.
Owing to organophosphorus functionality, chlorine/bromine substitution, a polycyclic aromatic system, (3-Bromobenzyl)triphenylphosphonium chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 467.77 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-Bromobenzyl)triphenylphosphonium chloride 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.
