Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Phenyldi(pyren-1-yl)phosphine oxide.
Phenyldi(pyren-1-yl)phosphine oxide (CAS 721969-93-3), molecular formula C38H23OP and molecular weight 526.56 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Phenyldi(pyren-1-yl)phosphine oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 526.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Phenyldi(pyren-1-yl)phosphine oxide 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.
