Description

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

CATO supplies (2R,3R)-(-)-2,3-Bis(diphenylphosphino)bicyclo[2.2.1]hept-5-ene (CAS 76740-45-9), a certified reference material (molecular formula C31H30P2, MW 464.52 g/mol) for analytical method development and quality control.

Structurally, (2R,3R)-(-)-2,3-Bis(diphenylphosphino)bicyclo[2.2.1]hept-5-ene (C31H30P2) contains organophosphorus functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 464.52 g/mol, it falls into the moderately-high-molecular-weight range. 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).

CATO manufactures (2R,3R)-(-)-2,3-Bis(diphenylphosphino)bicyclo[2.2.1]hept-5-ene 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.
