Chemical Structure
Description
CATO supplies 2-methanesulfonylcyclopropane-1,1-dicarboxylic acid (CAS 2059948-72-8), a certified reference material (molecular formula C6H8O6S, MW 208.19 g/mol) for analytical method development and quality control.
The molecular framework of 2-methanesulfonylcyclopropane-1,1-dicarboxylic acid (C6H8O6S) is characterized by a carbohydrate-derived structure, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
As a certified reference material (CRM), 2-methanesulfonylcyclopropane-1,1-dicarboxylic 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.
