Compared with other compounds in its class, the molecular weight of 530.53 g/mol gives [[(4S,5S)-5-[(Diphenylphosphinyl)methyl]-2,2-dimethyl-1,3-dioxolan-4-yl]methyl]diphenylphosphine oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
[[(4S,5S)-5-[(Diphenylphosphinyl)methyl]-2,2-dimethyl-1,3-dioxolan-4-yl]methyl]diphenylphosphine oxide (CAS 187989-59-9), molecular formula C31H32O4P2 and molecular weight 530.53 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of [[(4S,5S)-5-[(Diphenylphosphinyl)methyl]-2,2-dimethyl-1,3-dioxolan-4-yl]methyl]diphenylphosphine oxide (C31H32O4P2) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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. 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 [[(4S,5S)-5-[(Diphenylphosphinyl)methyl]-2,2-dimethyl-1,3-dioxolan-4-yl]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.
