Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1′-[(6R,8R,13aS)-3,11-Bis(1,1-dimethylethyl)-7,8-dihydro-6,8-dimethyl-6H-dibenzo[f,h][1,5]dioxonin-1,13-diyl]bis[1,1-diphenylphosphine].

1,1′-[(6R,8R,13aS)-3,11-Bis(1,1-dimethylethyl)-7,8-dihydro-6,8-dimethyl-6H-dibenzo[f,h][1,5]dioxonin-1,13-diyl]bis[1,1-diphenylphosphine] (CAS 1048328-92-2), molecular formula C50H52O2P2 and molecular weight 746.89 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,1′-[(6R,8R,13aS)-3,11-Bis(1,1-dimethylethyl)-7,8-dihydro-6,8-dimethyl-6H-dibenzo[f,h][1,5]dioxonin-1,13-diyl]bis[1,1-diphenylphosphine] (C50H52O2P2) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 25.0, corresponding to approximately 25 ring(s) or double-bond equivalent(s). With a molecular weight of 746.89 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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

As a certified reference material (CRM), 1,1′-[(6R,8R,13aS)-3,11-Bis(1,1-dimethylethyl)-7,8-dihydro-6,8-dimethyl-6H-dibenzo[f,h][1,5]dioxonin-1,13-diyl]bis[1,1-diphenylphosphine] 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.
