Acetylsalicylic acid CAS#50-78-2

Basic Information

Acetylsalicylic acid
Aspirin

Acetylsalicylic acid, also known as aspirin, is a pharmaceutical compound with limited water solubility and greater solubility in organic solvents. It also dissolves in alkaline solutions, where decomposition may occur, and hydrolysis produces salicylic acid and acetic acid. Alongside pharmaceutical raw-material applications, the supplied material identifies a role in the synthesis of rodenticide intermediates.

product description

Effective Anti-Inflammatory and Pain Relief: Aspirin acts as a nonsteroidal anti-inflammatory drug (NSAID), providing reliable reduction of inflammation and alleviation of pain in a wide range of conditions.


Anti-Thrombotic and Cardiovascular Protection: Aspirin helps prevent platelet aggregation, supporting cardiovascular health by reducing the risk of blood clot formation and contributing to the prevention of thrombotic events.


Reduction of Mortality from Heart Attack and Stroke: Regular use of aspirin has been shown to lower the mortality rate associated with myocardial infarction and ischemic stroke, making it a valuable intervention in high-risk patients.


Potential Cancer Risk Reduction: Emerging research indicates that aspirin may reduce the risk of developing colorectal cancer, highlighting its potential benefits beyond traditional cardiovascular and pain-relief applications.


Product Description of Acetylsalicylic Acid CAS#50-78-2

Aspirin, or acetylsalicylic acid, is a classic NSAID for anti-inflammation and pain relief. It inhibits platelet aggregation to prevent thrombosis, helping cut mortality from heart attack and stroke, and may also lower colorectal cancer risks.


Product Application of Acetylsalicylic Acid CAS#50-78-2

Acetylsalicylic acid is a key raw material for rodenticide intermediate synthesis, and hydrolyzes into salicylic acid and acetic acid. It is slightly soluble in water and easily soluble in organic solvents and alkaline solutions with possible decomposition.

Medically, it relieves fever, pain and rheumatism, facilitates uric acid excretion, inhibits platelet aggregation and treats biliary ascariasis.

It is also applied to durable outdoor structural parts and traffic markings for its stable protective performance.
