N-(3-Chlorophenyl)anthranilic acid, commonly known as meclofenamic acid, is a nonsteroidal anti-inflammatory drug (NSAID) utilized directly in the pharmaceutical industry for treating pain, inflammation, and fever. It functions by inhibiting cyclooxygenase (COX) enzymes, reducing prostaglandin synthesis. As an active pharmaceutical ingredient (API), it is prescribed for conditions like arthritis and menstrual pain. Additionally, it serves as a valuable intermediate and building block in the synthesis of related APIs and novel therapeutic agents in medicinal chemistry research. Its unique structure also makes it useful in organic synthesis for developing more complex molecules.
