Chemical Structure
Description
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.
CATO supplies 1-((5-Chloro-2-ethoxyphenyl)sulfonyl)piperidine-4-carboxylic acid (CAS 915909-89-6), a certified reference material (molecular formula C14H18ClNO5S, MW 347.81 g/mol) for analytical method development and quality control.
The molecular framework of 1-((5-Chloro-2-ethoxyphenyl)sulfonyl)piperidine-4-carboxylic acid (C14H18ClNO5S) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 1-((5-Chloro-2-ethoxyphenyl)sulfonyl)piperidine-4-carboxylic acid 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.
