CATO supplies 1,1′-[(5S)-2,2′,3,3′-Tetrahydro[5,5′-bi-1,4-benzodioxin]-6,6′-diyl]bis[1,1-bis[3,5-bis(trimethylsilyl)phenyl]phosphine] (CAS 2757287-32-2), a certified reference material (molecular formula C40H54O4P2Si4, MW 773.14 g/mol) for analytical method development and quality control.

1,1′-[(5S)-2,2′,3,3′-Tetrahydro[5,5′-bi-1,4-benzodioxin]-6,6′-diyl]bis[1,1-bis[3,5-bis(trimethylsilyl)phenyl]phosphine] (C40H54O4P2Si4) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 1,1′-[(5S)-2,2′,3,3′-Tetrahydro[5,5′-bi-1,4-benzodioxin]-6,6′-diyl]bis[1,1-bis[3,5-bis(trimethylsilyl)phenyl]phosphine] 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.
