(S)-(+)-4,4'-Bis[di(3,5-di-tert-butyl-4-methoxyphenyl)phosphino]-3,3'-bi(1,2-methylenedioxybenzene) (S)-(+)-5,5'-Bis[di(3,5-di-tert-butyl-4-methoxyphenyl)phosphino]-4,4'-bi-1,3-benzodioxole (S)-(+)-DTBM-SEGPHOS(regR) 210169-40-7 D4500 (CAS 210169-40-7), molecular formula C74H136O8P2 and molecular weight 1215.81 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-(+)-4,4'-Bis[di(3,5-di-tert-butyl-4-methoxyphenyl)phosphino]-3,3'-bi(1,2-methylenedioxybenzene) (S)-(+)-5,5'-Bis[di(3,5-di-tert-butyl-4-methoxyphenyl)phosphino]-4,4'-bi-1,3-benzodioxole (S)-(+)-DTBM-SEGPHOS(regR) 210169-40-7 D4500 (C74H136O8P2) 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 the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
