Chemical Structure
Description
Bis(hydroxymethyl)diphenylphosphonium chloride (CAS 96776-80-6), molecular formula C14H16O2PCl and molecular weight 282.70 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H16O2PCl, Bis(hydroxymethyl)diphenylphosphonium chloride contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 282.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Bis(hydroxymethyl)diphenylphosphonium 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.
