Products Description of Acetylsalicylic acid CAS#50-78-2
Aspirin, also known as acetylsalicylic acid, is a nonsteroidal anti-inflammatory drug and was first used for anti-inflammatory and analgesic purposes. Later, scientists discovered that aspirin can prevent platelet aggregation and achieve anti-thrombotic effects. As research on aspirin continues to deepen, many new uses have been discovered. For example, aspirin can reduce the mortality rate of myocardial infarction and stroke, and can also reduce the risk of colorectal cancer.

Product Application of Acetylsalicylic acid CAS#50-78-2
Acetylsalicylic acid is the raw material for preparing 4-hydroxycoumarin, an intermediate of rodenticide.
Salicylic acid and acetic acid. Slightly soluble in water, soluble in ethanol, ether, chloroform, and also soluble in alkali hydroxide solution or carbonic acid solution, and decomposes at the same time. Commonly used antipyretic and analgesic. Used for antipyretic, analgesic, anti-rheumatic, promoting the excretion of uric acid in gout patients, anti-platelet aggregation and biliary ascariasis treatment.
Used to manufacture outdoor and strong light exposure structural parts, equipment parts, such as car bodies, agricultural machinery parts, electric meters and lampshades, road markings, etc.
Antipyretic and analgesic, used for fever, pain and rheumatoid arthritis, etc.
