Description

Acetylsalicylic Acid CAS NO 50-78-2 is a white, crystalline organic compound widely recognized as the active pharmaceutical ingredient (API) in aspirin. It is a critical intermediate and final product in the pharmaceutical industry, valued for its analgesic, antipyretic, and anti-inflammatory properties. This essential chemical is primarily required by manufacturers in the pharmaceutical, nutraceutical, and fine chemical synthesis sectors.

Application

• Pharmaceutical API: Primary use as the active ingredient in analgesic, antipyretic, and anti-inflammatory medications (e.g., aspirin tablets).
• Cardiovascular Prophylaxis: Manufacture of low-dose aspirin formulations used for antiplatelet therapy to prevent heart attacks and strokes.
• Chemical Synthesis: Serves as a key starting material or intermediate in the synthesis of more complex pharmaceutical compounds and dyes.
• Veterinary Medicine: Used in formulations for pain and fever management in animals.
• Research & Development: Utilized in biochemical and pharmacological research as a standard COX inhibitor.
• Industrial Applications: Potential use in polymer modification and as a stabilizer in certain industrial processes.
