Chemical Structure
Description
The molecular framework of Dimethyl (1R,2S)-4,5-dimethylcyclohex-4-ene-1,2-dicarboxylate (C12H18O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
CATO supplies Dimethyl (1R,2S)-4,5-dimethylcyclohex-4-ene-1,2-dicarboxylate (CAS 55264-91-0), a certified reference material (molecular formula C12H18O4, MW 226.27 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
