N-(1-(4-Methylpiperazin-1-yl)-1-(thiophen-2-yl)propan-2-yl)benzenesulfonamide CAS 847381-04-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(1-(4-Methylpiperazin-1-yl)-1-(thiophen-2-yl)propan-2-yl)benzenesulfonamide.

N-(1-(4-Methylpiperazin-1-yl)-1-(thiophen-2-yl)propan-2-yl)benzenesulfonamide (CAS 847381-04-8), molecular formula C18H25N3O2S2 and molecular weight 379.54 g/mol, is a CATO reference standard with documented purity and traceability.

N-(1-(4-Methylpiperazin-1-yl)-1-(thiophen-2-yl)propan-2-yl)benzenesulfonamide (C18H25N3O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
