CAS 50-78-2: Aspirin

Description: Aspirin, chemically known as acetylsalicylic acid, is a widely used pharmaceutical compound with the CAS number 50-78-2. It is classified as a nonsteroidal anti-inflammatory drug (NSAID) and is primarily utilized for its analgesic, antipyretic, and anti-inflammatory properties. Aspirin works by inhibiting the enzyme cyclooxygenase (COX), which plays a crucial role in the synthesis of prostaglandins, compounds involved in pain and inflammation. The substance appears as a white crystalline powder and is sparingly soluble in water but more soluble in organic solvents like ethanol and acetone. Aspirin is commonly administered in tablet form and is known for its ability to reduce fever, alleviate mild to moderate pain, and lower the risk of cardiovascular events due to its antiplatelet effects. However, it can cause gastrointestinal irritation and is contraindicated in certain populations, such as children with viral infections due to the risk of Reye's syndrome. Overall, aspirin remains a cornerstone in both over-the-counter and prescription medication regimens.
