Molecular Structure:

Property:
Menthol is an organic compound made synthetically or obtained from peppermint or other mint oils. Menthol is a waxy, crystalline substance, clear or white in color, which is solid at room temperature and melts slightly above. The main form of menthol occurring in nature is (? )-menthol, which is assigned the (1R, 2S, 5R) configuration. Menthol has local anesthetic and counterirritant qualities, and menthol is widely used to relieve minor throat irritation. Menthol also acts as a weak kappa Opioid receptor agonist. Menthol's ability to chemically trigger the cold-sensitive TRPM8 receptors in the skin is responsible for the well known cooling sensation that it provokes when inhaled, eaten, or applied to the skin. In this sense menthol is similar to capsaicin, the chemical responsible for the spiciness of hot peppers (which stimulates heat sensors, also without causing an actual change in temperature). Menthol has analgesic properties that are mediated through a selective activation of κ -opioid receptors. Menthol also enhances the efficacy of ibuprofen in topical applications via vasodilation, which reduces skin barrier function.

Usage:
In some beauty products such as hair-conditioners, based on natural ingredients (e. G. St. Ives)
In organic chemistry, menthol is used as a chiral auxiliary in asymmetric synthesis. For example, sulfinate esters made from sulfinyl chlorides and menthol can be used to make enantiomerically pure sulfoxides by reaction with organolithium reagents or Grignard reagents. Menthol reacts with chiral carboxylic acids to give diastereomic menthyl esters, which are useful for chiral resolution.
