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 Ethyl 2-iodo-2-(triphenylphosphoranylidene)acetate.
CATO supplies Ethyl 2-iodo-2-(triphenylphosphoranylidene)acetate (CAS 26480-87-5), a certified reference material (molecular formula C22H20IO2P, MW 474.27 g/mol) for analytical method development and quality control.
Structurally, Ethyl 2-iodo-2-(triphenylphosphoranylidene)acetate (C22H20IO2P) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 474.27 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), Ethyl 2-iodo-2-(triphenylphosphoranylidene)acetate 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.
