Chemical Structure

(S,S)-1,2-Bis[(2-methylphenyl)-(phenyl)phosphino]ethane CAS 810667-85-7 chemical structure

Description

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

(S,S)-1,2-Bis[(2-methylphenyl)-(phenyl)phosphino]ethane (CAS 810667-85-7) is a high-purity analytical reference standard with the molecular formula C28H28P2 and a molecular weight of 426.47 g/mol.

(S,S)-1,2-Bis[(2-methylphenyl)-(phenyl)phosphino]ethane (C28H28P2) contains organophosphorus functionality, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

CATO manufactures (S,S)-1,2-Bis[(2-methylphenyl)-(phenyl)phosphino]ethane 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.
