1,2-Bis(diphenylphosphino)benzene CAS 13991-08-7 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.

1,2-Bis(diphenylphosphino)benzene (CAS 13991-08-7), molecular formula C30H24P2 and molecular weight 446.46 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to organophosphorus functionality, a polycyclic aromatic system, 1,2-Bis(diphenylphosphino)benzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 446.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

As a certified reference material (CRM), 1,2-Bis(diphenylphosphino)benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
