(2-Ethoxy-1-iodo-2-oxoethyl)triphenylphosphonium iodide CAS 111598-99-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2-Ethoxy-1-iodo-2-oxoethyl)triphenylphosphonium iodide.

(2-Ethoxy-1-iodo-2-oxoethyl)triphenylphosphonium iodide (CAS 111598-99-3) is a high-purity analytical reference standard with the molecular formula C22H21IO2PI and a molecular weight of 602.18 g/mol.

Based on its molecular formula C22H21IO2PI, (2-Ethoxy-1-iodo-2-oxoethyl)triphenylphosphonium iodide contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 602.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (2-Ethoxy-1-iodo-2-oxoethyl)triphenylphosphonium iodide 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.
