Salicylic Acid

Salicylic Acid
Salicylic Acid is a white crystalline powder or needle-shaped crystals with sweetish taste.

Salicylic acid is a beta hydroxy acid (BHA) with the formula C6H4(OH)CO2H, where the OH group is adjacent to the carboxyl group. This organic acid is widely used in organic synthesis and functions as a plant hormone. It is derived from the metabolism of salicin. It is probably best known as a compound that is chemically similar to but not identical to the active component of aspirin (acetylsalicylic acid).
