Chemical Structure

3-fluoro-4-(pyrrolidin-2-ylmethoxy)benzene-1-sulfonamide hydrochloride CAS 1864061-23-3 chemical structure

Description

The occurrence of 3-fluoro-4-(pyrrolidin-2-ylmethoxy)benzene-1-sulfonamide 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.

3-fluoro-4-(pyrrolidin-2-ylmethoxy)benzene-1-sulfonamide hydrochloride (CAS 1864061-23-3), molecular formula C11H15FN2O3SHCl and molecular weight 310.77 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-fluoro-4-(pyrrolidin-2-ylmethoxy)benzene-1-sulfonamide hydrochloride (C11H15FN2O3SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
