Ethyl vanillin
I-Ethyl vanillin iyindawo ye-organic ngefomula (C2H5O) (ho) c6h3cho. Le solid engenamibala iqukethe indandatho ye-benzene ene-hydroxyl, ama-ethaxy, namaqembu ama-mbumbulu ezikhundleni 4, 3, kanye nezikhundla ezi-1, ngokulandelana.
I-Ethyl vanillin yi-molecule yokwenziwa, engatholakali emvelweni. Ilungiselelwe ngezinyathelo eziningana kusuka ku-Catechol, ukuqala ngokuthambisa ukunikeza "i-guethol". Le ether condenses nge-glyoxylic acid ukunikeza i-malelic acid ehambisanayo, eyi-ngexidation kanye ne-decarboxylation inika i-ethyl vanillin.
Njengoba i-flavont, i-ethyl vanillin icishe ibe kathathu njenge-vanillin futhi isetshenziswa ekukhiqizweni koshokoledi.
