Chemical Structure

2-(Cyclopentanesulfonyl)aniline, HCl CAS 1355248-12-2 chemical structure

Description

The occurrence of 2-(Cyclopentanesulfonyl)aniline, HCl is closely related to a nitrogen-containing heterocyclic scaffold, 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.

CATO supplies 2-(Cyclopentanesulfonyl)aniline, HCl (CAS 1355248-12-2), a certified reference material (molecular formula C11H15NO2SHCl, MW 261.76 g/mol) for analytical method development and quality control.

2-(Cyclopentanesulfonyl)aniline, HCl (C11H15NO2SHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 2-(Cyclopentanesulfonyl)aniline, HCl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
