Salicylaldehyde CAS#90-02-8

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.
