(1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Quality Control of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol

Volatile organic compounds (VOCs) are the main chem. components of Schizonepetae Spica (SS), which have pos. effects on the quality evaluation of SS. In this study, HS-SPME-GC-MS (headspace solid-phase microextraction-gas chromatog.-mass spectrometry) and HS-GC-IMS (headspace-gas chromatog.-ion mobility spectrometry) were performed to characterize the VOCs of SS from six different regions. A total of 82 VOCs were identified. In addition, this work compared the suitability of two instruments to distinguish SS from different habitats. The regional classification using orthogonal partial least squares discriminant anal. (OPLS-DA) shows that the HS-GC-IMS method can classify samples better than the HS-SPME-GC-MS. This study provided a reference method for identification of the SS from different origins. In the experiment, the researchers used many compounds, for example, (1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5Quality Control of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol).
