The "biological source" entry of "synthetic (organic)" in the properties table for this product indicates that the material is of entirely synthetic origin. The type of chemical synthesis used is organic synthesis, which involves the construction of chemical compounds containing carbon. Definitions for organic compounds often specify the presence of a carbon-carbon or carbon-hydrogen bond.

General description
(1R,2S,5R)-(-)-Menthol is a monoterpene.[1]
Application
(1R,2S,5R)-(-)-Menthol may be used to synthesize:
- chiral enantiopure 2-(1-hydroxyalkyl)pyridines, which can react with to form C3-symmetric tripodal ligands[2]
- menthylphosphorodichioridite, a chiral derivatizing agent for the determination of enantiomeric purity of chiral diols or diamines by 31P NMR spectroscopy[3]
- (2R,4S)-2,3,4,5-tetrahydro-2-(-)-menthyloxy-2-methyl-4-phenylpyrano-[3,2-c]-benzopyran-5-one, an intermediate to prepare a warfarin analog[4]

Good morning. I am interested in the product M2780, (1R,2S,5R)-(−)-Menthol. But I noticed that in the item of "biological source", the information is synthetic (organic). I would like to know what the word organic means here.
