2-methylpyrazine has been used as a food additive due to its nutty aroma. It has also been declared to smell like potato, cocoa, and to give a musty scent. The measured odor
detection threshold of this compound in water is 60,000ppb. 2-methylpyrazine is used as an AWA
odorant in experiments with worms because it causes a more rapid adaptation of
the neurons than any other odorants. These studies focus on the olfactory
plasticity in C. elegans. AWA is an amphid sensory neuron which detects certain odors. 2-methyl pyrazine is also one of the 599 additives in cigarettes as well as an odorant in popcorn.
