Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(Hydroxymethyl)triphenylphosphonium chloride (CAS 5293-83-4), molecular formula C19H18OPCl and molecular weight 328.78 g/mol, is a CATO reference standard with documented purity and traceability.
(Hydroxymethyl)triphenylphosphonium chloride (C19H18OPCl) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (Hydroxymethyl)triphenylphosphonium chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
