Chemical Structure
Description
Methyl 3-methoxy-1-methyl-6-oxocyclohex-2-enecarboxylate (CAS 1314974-88-3) is a high-purity analytical reference standard with the molecular formula C10H14O4 and a molecular weight of 198.22 g/mol.
Methyl 3-methoxy-1-methyl-6-oxocyclohex-2-enecarboxylate (C10H14O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Methyl 3-methoxy-1-methyl-6-oxocyclohex-2-enecarboxylate 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.
