Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Sodiumphenylphosphinate (CAS 4297-95-4), a certified reference material (molecular formula C6H6O2PNa, MW 164.08 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H6O2PNa, Sodiumphenylphosphinate contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 164.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Sodiumphenylphosphinate 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.
