描述
4-hydroxy-3,5-dimethoxybenzaldehyde, also known as sinapaldehyde or 2,6-dimethoxy-4-formylphenol, is a member of the class of compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. 4-hydroxy-3,5-dimethoxybenzaldehyde is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 4-hydroxy-3,5-dimethoxybenzaldehyde is a mild, sweet, and plastic tasting compound and can be found in a number of food items such as whisky, common grape, garden tomato (variety), and coriander, which makes 4-hydroxy-3,5-dimethoxybenzaldehyde a potential biomarker for the consumption of these food products. 4-hydroxy-3,5-dimethoxybenzaldehyde may be a unique S.cerevisiae (yeast) metabolite. Because it contains many functional groups, it can be classified in many ways - aromatic, aldehyde, phenol. It is a colorless solid (impure samples appear yellowish) that is soluble in alcohol and polar organic solvents. Its refractive index is 1.53 .
