Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ((Methylsulfonyl)methyl)diphenylphosphine oxide.
((Methylsulfonyl)methyl)diphenylphosphine oxide (CAS 59625-05-7), molecular formula C14H15O3PS and molecular weight 294.31 g/mol, is a CATO reference standard with documented purity and traceability.
((Methylsulfonyl)methyl)diphenylphosphine oxide (C14H15O3PS) contains a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures ((Methylsulfonyl)methyl)diphenylphosphine 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.
