Description
CATO manufactures 3-(Triphenyl-l5-phosphaneylidene)pentane-2,4-dione 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.
3-(Triphenyl-l5-phosphaneylidene)pentane-2,4-dione (CAS 1474-32-4) is a high-purity analytical reference standard with the molecular formula C23H21O2P and a molecular weight of 360.39 g/mol.
The molecular framework of 3-(Triphenyl-l5-phosphaneylidene)pentane-2,4-dione (C23H21O2P) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
