Chemical Structure

N-(4-((4-(4-Chlorophenyl)piperazin-1-yl)sulfonyl)phenyl)acetamide CAS 445252-20-0 chemical structure

Description

The occurrence of N-(4-((4-(4-Chlorophenyl)piperazin-1-yl)sulfonyl)phenyl)acetamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-(4-((4-(4-Chlorophenyl)piperazin-1-yl)sulfonyl)phenyl)acetamide (CAS 445252-20-0), molecular formula C18H20ClN3O3S and molecular weight 393.89 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-(4-((4-(4-Chlorophenyl)piperazin-1-yl)sulfonyl)phenyl)acetamide (C18H20ClN3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 393.89 g/mol, it falls into the moderately-high-molecular-weight range. 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.
