3-METHYL-GAMMA-OCTALACTONE.

Optional CAS 39212-23-2 / PERFUMING

A gamma-lactone compound, also known as whiskey lactone, that serves as a fragrance component with a distinctive sweet, coconut-like aroma. While primarily utilized for its olfactory properties, this lactone structure may offer secondary skin-conditioning benefits through potential antioxidant activity.
