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 (4-Iodophenyl)(phenyl)phosphinicacid.
(4-Iodophenyl)(phenyl)phosphinicacid (CAS 54185-74-9), molecular formula C12H10IO2P and molecular weight 344.08 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4-Iodophenyl)(phenyl)phosphinicacid (C12H10IO2P) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 344.08 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (4-Iodophenyl)(phenyl)phosphinicacid 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.
