Chemical Structure

(S)-2,2’-Bis(di-p-tolylphosphino)-1,1’-binaphthalene CAS 100165-88-6 chemical structure

Description

(S)-2,2’-Bis(di-p-tolylphosphino)-1,1’-binaphthalene (CAS 100165-88-6), molecular formula C48H40P2 and molecular weight 678.78 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to organophosphorus functionality, a polycyclic aromatic system, (S)-2,2’-Bis(di-p-tolylphosphino)-1,1’-binaphthalene is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 678.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

CATO manufactures (S)-2,2’-Bis(di-p-tolylphosphino)-1,1’-binaphthalene 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.
