Borneol flakes
Borneol exists as two enantiomers which have two different cas numbers. Naturally occurring d-(+)-borneol is optically active. It can be found in several species of artemisia and dipterocarpaceae.
Borneol is used in traditional chinese medicine as moxa. Borneol is also a component of many essential oils, and it is a natural insect repellent.

Colorless or white transparent flaky brittle crystals, or crystalline powders and blocks. It has a strong smell of rosin, camphor and mint. It can sublimate when heated and volatilize slowly at room temperature, with a burning sensation. Melting point 208 �ºC (racemate), boiling point 212 �ºC, flash point 65.6chemical book �ºC, relative density 1.011 (20 �ºC). Insoluble in water, soluble in ethanol, ether and chloroform. Natural levorosomes exist in nutmeg, cardamom, ginger, etc., dextrorosomes exist in coriander seeds, citronella, etc., and racemes exist in camphor, rosemary, thyme, etc.
Application
Edible spices. It is mainly used to prepare mint, white lemon, nut, rosemary, lavender and other essence.
It is widely used in the pharmaceutical industry as a biochemical reagent.
Used for manufacturing borneol esters, spices, etc.
