Chemical Structure

2-Hydroxy-3,4-dimethylcyclopent-2-en-1-one CAS 21835-00-7 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 2-Hydroxy-3,4-dimethylcyclopent-2-en-1-one (CAS 21835-00-7), a certified reference material (molecular formula C7H10O2, MW 126.15 g/mol) for analytical method development and quality control.

The molecular framework of 2-Hydroxy-3,4-dimethylcyclopent-2-en-1-one (C7H10O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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).

As a certified reference material (CRM), 2-Hydroxy-3,4-dimethylcyclopent-2-en-1-one 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.
