Salicylic acid, also known as salicylic acid, is a white crystalline powder, odorless, with a slightly bitter taste and then acrid. The acidity is stronger than that of benzoic acid, and the color becomes darker in sunlight. It turns into a purple-red chelate when it encounters iron ions. It reacts with ferric chloride and turns purple. It is not stable to heat. Salicylic acid is an important organic synthetic raw material and is widely used in rubber, dye, food and fragrance industries.
Salicylic acid, also known as o-hydroxybenzoic acid, is an important raw material for organic synthesis. It is used to synthesize isopropyl salicylate, methyl isoflophos; it is also an important raw material for dyes, spices, rubber and other industries.
