Methyl (2Z)-3-[(4-chloro-2-fluorophenyl)amino]-2-phenylbut-2-enoate CAS 478041-31-5

Description

The occurrence of Methyl (2Z)-3-[(4-chloro-2-fluorophenyl)amino]-2-phenylbut-2-enoate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl (2Z)-3-[(4-chloro-2-fluorophenyl)amino]-2-phenylbut-2-enoate (CAS 478041-31-5) is a high-purity analytical reference standard with the molecular formula C17H15ClFNO2 and a molecular weight of 319.76 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Methyl (2Z)-3-[(4-chloro-2-fluorophenyl)amino]-2-phenylbut-2-enoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
