4-((4-Fluorophenyl)thio)-N-(4-methoxyphenyl)butanamide CAS 941925-12-8

Description

The occurrence of 4-((4-Fluorophenyl)thio)-N-(4-methoxyphenyl)butanamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-((4-Fluorophenyl)thio)-N-(4-methoxyphenyl)butanamide (CAS 941925-12-8) is a high-purity analytical reference standard with the molecular formula C17H18FNO2S and a molecular weight of 319.39 g/mol.

4-((4-Fluorophenyl)thio)-N-(4-methoxyphenyl)butanamide (C17H18FNO2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
