A common over-the-counter pain reliever and fever reducer, known as paracetamol outside North America.
Chemical name derived from its molecular structure: acetyl + amino + phenol. Synthesized in 1877 but not used medicinally until the 1950s when its safety profile was better understood.
Acetaminophen was actually discovered decades before aspirin but took much longer to reach market because early researchers didn't realize they needed to remove toxic impurities—a reminder that timing in medicine depends on both discovery and understanding.
