The occurrence of Ethyl 6-Isopropyl-2-methyl-4-oxo-2-cyclohexenecarboxylate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 6-Isopropyl-2-methyl-4-oxo-2-cyclohexenecarboxylate (CAS 24079-95-6) is a high-purity analytical reference standard with the molecular formula C13H20O3 and a molecular weight of 224.30 g/mol.
The molecular framework of Ethyl 6-Isopropyl-2-methyl-4-oxo-2-cyclohexenecarboxylate (C13H20O3) 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.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
