Chemically Aspirin is______.

  • A.Salicylic Acid
  • B.Indole Acetic Acid
  • C.Propionic Acid
  • D.Anthranilic Acid

Answer: A

The answer is Salicylic Acid.

Strictly, aspirin is acetylsalicylic acid, the acetyl ester of salicylic acid, made by acetylating salicylic acid with acetic anhydride. Chemically it belongs to the salicylic acid derivatives (salicylates), and that is the classification the key accepts: salicylic acid is the only option that is aspirin's parent compound.

The other options are the parent acids of other NSAID groups. Indole acetic acid is the parent of indomethacin, propionic acid of ibuprofen and naproxen, and anthranilic acid of the fenamates such as mefenamic acid.
