| 2-Methoxy-3-isobutyl pyrazine Usage And Synthesis |
| 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 | 2-Isobutyl-3-methoxypyrazine has a green bell pepper, green pea odor. Diluted water solutions of this compound exhibit a characteristic odor of green bell peppers. |
| Chemical Properties | CLEAR COLOURLESS LIQUID |
| Occurrence | Reported present in green bell pepper, coffee, galbanum oil, potato products, peas, grapes, lettuce, sherry, white wine, cocoa, beans, beetroot, passion fruit and okra. |
| Uses | 2-Isobutyl-3-methoxypyrazine has been employed as a model odorant molecule during an electrochemical assay for the detection of odorant molecules based on a rat odorant-binding protein (rOBP3). |
| Preparation | By condensation of leucine amide with glyoxal followed by methylation with CH2H2 |
| Aroma threshold values | Detection: 2 ppt to 10 ppb |
| General Description | 2-Isobutyl-3-methoxypyrazine, a potent bell-pepper odourant, has been found to bind to cow olfactory mucosa homogenate. |
