描述
Isovaleraldehyde diethyl acetal is a member of the class of compounds known as acetals. Acetals are compounds having the structure R2C(OR')2 ( R' not Hydrogen) and thus diethers of geminal diols. Originally, the term was confined to derivatives of aldehydes (one R = H), but it now applies equally to derivatives of ketones (neither R = H ). Mixed acetals have different R' groups. Isovaleraldehyde diethyl acetal is slightly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Isovaleraldehyde diethyl acetal is a fatty and fruity tasting compound and can be found in a number of food items such as green bell pepper, yellow bell pepper, orange bell pepper, and red bell pepper, which makes isovaleraldehyde diethyl acetal a potential biomarker for the consumption of these food products.
