Compared with other compounds in its class, the molecular weight of 552.71 g/mol gives (S,S)-2,4-Bis[bis(3,5-dimethylphenyl)phosphino]pentane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S,S)-2,4-Bis[bis(3,5-dimethylphenyl)phosphino]pentane (CAS 551950-92-6) is a high-purity analytical reference standard with the molecular formula C37H46P2 and a molecular weight of 552.71 g/mol.
The molecular framework of (S,S)-2,4-Bis[bis(3,5-dimethylphenyl)phosphino]pentane (C37H46P2) is characterized by organophosphorus functionality, 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 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.
