Retrieved 12 June Indian Journal of Microbiology. Retrieved 18 January The ChemSpider entry for MCHM indicates that it has been evaluated for ligand activity via SimBioSys ‘s LASSO analysis, which predicted low to no activity on 40 biologically significant receptorsindicating a low likelihood for significant biological activity on them.
One web site, Fantastic Flavours provides a list of recognized flavor additives for Japan, which includes 2,4-dimethylcyclohexanemethanol by virtue of being in the group of aliphatic higher alcohols.
This page was last edited on 10 Decemberat Canadian Journal of Research. Commercial samples of MCHM consists of a mixture of these isomers as well as other components that vary with the supplier. Another CHM derivative, 2,4-dimethylcyclohexanemethanol CASalso dihydrofloralol or floral methanolwhich has two methyl substituents instead of one, is frequently marketed as a fragrance or flavor additive.

The toxicity and environmental properties of these naphthenic acids have been well studied recently due to their occurrence as methannol major contaminant in water used for extraction of oil from tar sands. Journal of the Chemical Society Resumed: Journal of the Chemical Society, Transactions.
MCHM has the advantage of being less toxic than previous frothing agents containing 2-ethylhexanol.
The solubility of 1-octanol in water is 2. Both cis and trans isomers exist, depending on the relative positions of the methyl CH 3 and hydroxymethyl CH 2 OH groups on the cyclohexane ring. Ullmann’s Encyclopedia of Industrial Chemistry.
