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 (3-Hydroxy-3-phenylpropyl)diphenylphosphine oxide (CAS 22950-48-7), a certified reference material (molecular formula C14H18Cl4O2S4, MW 488.36 g/mol) for analytical method development and quality control.
The molecular framework of (3-Hydroxy-3-phenylpropyl)diphenylphosphine oxide (C14H18Cl4O2S4) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. 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), (3-Hydroxy-3-phenylpropyl)diphenylphosphine oxide 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.
