Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(4-Carboxybutyl-2,2,3,3-d4)triphenylphosphonium Bromide (CAS 42932-63-8) is a high-purity analytical reference standard with the molecular formula C23H20D4O2PBr and a molecular weight of 447.34 g/mol.
Owing to deuterium isotope labeling, a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution, (4-Carboxybutyl-2,2,3,3-d4)triphenylphosphonium Bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 447.34 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).
CATO manufactures (4-Carboxybutyl-2,2,3,3-d4)triphenylphosphonium Bromide 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.
