Description

General description

2-Methylisoborneol (2-MIB) is a semi-volatile compound, responsible for the undesirable earthy-musty odor in surface water. It can be efficiently degraded by TiO₂ photocatalysis. 2-MIB can also be easily adsorbed on granular activated carbon.

Application

2-Methylisoborneol can be used as a reactant:

• To prepare N-[(1R,2R,4R)-1,4,7,7-tetramethylbicyclo[2.2.1]hept-2-yl]acetamide by reacting with acetonitrile in the presence of boron trifluoride etherate.
• In the enantioselective total synthesis of geissoschizine as well as geissoschizol.

Other Notes

Fungal metabolite which contributes to the earthy odor in public water supplies.
