(S)-7,7′-Bis(diphenylphosphino)-3,3′,4,4′-tetrahydro-4,4′-dimethyl-8,8′-bi(2H-1,4-benzoxazine) CAS 649559-68-2

Description

As a certified reference material (CRM), (S)-7,7′-Bis(diphenylphosphino)-3,3′,4,4′-tetrahydro-4,4′-dimethyl-8,8′-bi(2H-1,4-benzoxazine) 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.

(S)-7,7′-Bis(diphenylphosphino)-3,3′,4,4′-tetrahydro-4,4′-dimethyl-8,8′-bi(2H-1,4-benzoxazine) (CAS 649559-68-2), molecular formula C42H38N2O2P2 and molecular weight 664.71 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, (S)-7,7′-Bis(diphenylphosphino)-3,3′,4,4′-tetrahydro-4,4′-dimethyl-8,8′-bi(2H-1,4-benzoxazine) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 664.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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