The occurrence of (2E)-N-(3-Iodo-4-methylphenyl)-3-[4-(2-methylpropyl)phenyl]prop-2-enamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (2E)-N-(3-Iodo-4-methylphenyl)-3-[4-(2-methylpropyl)phenyl]prop-2-enamide (CAS 329778-58-7), a certified reference material (molecular formula C20H22INO, MW 419.30 g/mol) for analytical method development and quality control.
Structurally, (2E)-N-(3-Iodo-4-methylphenyl)-3-[4-(2-methylpropyl)phenyl]prop-2-enamide (C20H22INO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 419.30 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.
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.
