N-(3-fluoro-4-(4-methylpiperazin-1-yl)phenyl)-2-((4-methoxyphenyl)thio)acetamide CAS 478260-46-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(3-fluoro-4-(4-methylpiperazin-1-yl)phenyl)-2-((4-methoxyphenyl)thio)acetamide.

N-(3-fluoro-4-(4-methylpiperazin-1-yl)phenyl)-2-((4-methoxyphenyl)thio)acetamide (CAS 478260-46-7), molecular formula C20H24FN3O2S and molecular weight 389.49 g/mol, is a CATO reference standard with documented purity and traceability.

N-(3-fluoro-4-(4-methylpiperazin-1-yl)phenyl)-2-((4-methoxyphenyl)thio)acetamide (C20H24FN3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
