(3-Amino-4-((4-chlorophenyl)sulfonyl)-5-(phenylamino)thiophen-2-yl)(phenyl)methanone CAS 866844-40-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-Amino-4-((4-chlorophenyl)sulfonyl)-5-(phenylamino)thiophen-2-yl)(phenyl)methanone.

(3-Amino-4-((4-chlorophenyl)sulfonyl)-5-(phenylamino)thiophen-2-yl)(phenyl)methanone (CAS 866844-40-8) is a high-purity analytical reference standard with the molecular formula C23H17ClN2O3S2 and a molecular weight of 468.98 g/mol.

(3-Amino-4-((4-chlorophenyl)sulfonyl)-5-(phenylamino)thiophen-2-yl)(phenyl)methanone (C23H17ClN2O3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
