4-(Pyrrolidin-1-yl)benzenesulfonyl chloride CAS 125393-18-2

Description

Compared with other compounds in its class, the molecular weight of 245.73 g/mol gives 4-(Pyrrolidin-1-yl)benzenesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(Pyrrolidin-1-yl)benzenesulfonyl chloride (CAS 125393-18-2), a certified reference material (molecular formula C10H12ClNO2S, MW 245.73 g/mol) for analytical method development and quality control.

The molecular framework of 4-(Pyrrolidin-1-yl)benzenesulfonyl chloride (C10H12ClNO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
