| Hazard Information | Back Directory | [Description]
2-Isobutyl-3-methoxypyrazine has an extremely powerful odor
with a reported threshold value of 2 parts per trillion in water.
Diluted water solutions exhibit a characteristic odor of green bell
peppers. May be synthesized by condensation of leucine amide
with glyoxal, followed by methylation with CH2H2. | [Chemical Properties]
