Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S,2R,5S)-2-Isopropyl-5-methylcyclohexyl 2-oxoacetate hydrate.
(1S,2R,5S)-2-Isopropyl-5-methylcyclohexyl 2-oxoacetate hydrate (CAS 208192-14-7) is a high-purity analytical reference standard with the molecular formula C12H22O4 and a molecular weight of 230.30 g/mol.
Based on its molecular formula C12H22O4, (1S,2R,5S)-2-Isopropyl-5-methylcyclohexyl 2-oxoacetate hydrate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 230.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
