Chemical Structure

(S)-3-fluoro-N-(pyrrolidin-3-yl)benzenesulfonamide hydrochloride CAS 1354018-70-4 chemical structure

Description

The occurrence of (S)-3-fluoro-N-(pyrrolidin-3-yl)benzenesulfonamide hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-3-fluoro-N-(pyrrolidin-3-yl)benzenesulfonamide hydrochloride (CAS 1354018-70-4) is a high-purity analytical reference standard with the molecular formula C10H13FN2O2SHCl and a molecular weight of 280.74 g/mol.

Structurally, (S)-3-fluoro-N-(pyrrolidin-3-yl)benzenesulfonamide hydrochloride (C10H13FN2O2SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 280.74 g/mol, it falls into the medium-molecular-weight range. 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.
