Description
CATO manufactures 1,8-Bis(diphenylphosphino)octane 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.
CATO supplies 1,8-Bis(diphenylphosphino)octane (CAS 41625-30-3), a certified reference material (molecular formula C32H36P2, MW 482.58 g/mol) for analytical method development and quality control.
The molecular framework of 1,8-Bis(diphenylphosphino)octane (C32H36P2) 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.
