What is Salicylaldehyde?
Description
Salicylaldehyde (2-hydroxybenzaldehyde) is an organic compound with the formula C6H4CHO-2-OH. Along with 3-hydroxybenzaldehyde and 4-hydroxybenzaldehyde, it is one of the three isomers of hydroxybenzaldehyde. It is a colorless or pale yellow liquid with a bitter almond odor and a burning taste. It is soluble in alcohol, benzene, and ether, and very slightly soluble in water. Salicylaldehyde is found in shrubs of the genus Spiraea and is usually produced from phenol by the action of chloroform in the presence of an alkali base. It is used in the production of coumarin, saligenin, and salicylaldoxime (an important analytical reagent), and also in analytical chemistry—for example, to detect hydrazine. Besides, salicylaldehyde is a key precursor to various chelating agents and a flavouring ingredient.
The Uses of Salicylaldehyde
Salicylaldehyde, is used as flavor and fragrance components. Salicylaldehyde is also a common highly-functionalized arene, that can be used as a precursor in the synthesis of other chemicals.
What are the applications of Application
Salicylaldehyde is a multi-functional arene synthesis reagent
