Chemical Structure
Description
CATO supplies Ethyl 2-(diethoxyphosphoryl)-2-(4-iodophenyl)acetate (CAS 152302-87-9), a certified reference material (molecular formula C14H20IO5P, MW 426.18 g/mol) for analytical method development and quality control.
Structurally, Ethyl 2-(diethoxyphosphoryl)-2-(4-iodophenyl)acetate (C14H20IO5P) contains a phosphate ester group, 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 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 426.18 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
