外観

無色～うすい黄褐色、液体

用途

有機合成原料。

説明

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.

化学的特性

CLEAR COLOURLESS LIQUID

天然物の起源

Reported present in green bell pepper, coffee, galbanum oil, potato products, peas, grapes, lettuce, sherry, white wine, cocoa, beans, beetroot, passion fruit and okra.

使用

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).

製造方法

By condensation of leucine amide with glyoxal followed by methylation with CH2H2

一般的な説明

2-Isobutyl-3-methoxypyrazine, a potent bell-pepper odourant, has been found to bind to cow olfactory mucosa homogenate.
