Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethynyl(diphenyl)phosphine Oxide (CAS 6104-48-9), molecular formula C14H11OP and molecular weight 226.21 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H11OP, Ethynyl(diphenyl)phosphine Oxide contains organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 226.21 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.
CATO manufactures Ethynyl(diphenyl)phosphine Oxide 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.
