Why is acetylsalicylic acid in aspirin?
Aspirin is an orally administered non-steroidal antiinflammatory agent. Acetylsalicylic acid binds to and acetylates serine residues in cyclooxygenases, resulting in decreased synthesis of prostaglandin, platelet aggregation, and inflammation. This agent exhibits analgesic, antipyretic, and anticoagulant properties.
Is salicylic acid in aspirin?
This unique drug belongs to a family of compounds called the salicylates, the simplest of which is salicylic acid, the principal metabolite of aspirin. Salicylic acid is responsible for the anti-inflammatory action of aspirin, and may cause the reduced risk of colorectal cancer observed in those who take aspirin.
Is aspirin made of salicylic acid?
Aspirin is prepared by chemical synthesis from salicylic acid, through acetylation with acetic anhydride. The molecular weight of aspirin is 180.16g/mol.
What is acetylsalicylic acid known as?
Acetylsalicylic acid (ASA), also known as aspirin, acts by irreversibly inhibiting the platelet cyclooxygenase (COX) enzyme, resulting in inhibition of platelet thromboxane A2 (TXA-2) synthesis.
Is aspirin a salicylic acid?
Is aspirin a carboxylic acid?
Aspirin is both an aromatic carboxylic acid (red oval) and a phenyl ester of acetic acid (blue oval). While esterification will convert the carboxylic acid group to a methyl ester, transesterification (exchange of one alcohol portion of an ester for another alcohol) to afford methyl acetate 4 and methyl salicylate 3.
Is Asa the same as salicylic acid?
Salicylic acid is not the same thing as aspirin. The two medicines are related, and have similar-sounding chemical names. Aspirin is also known as acetylsalicylic acid, which is created by a chemical reaction between salicylic acid and acetic acid.
How much salicylic acid is in aspirin?
In the presence of moisture, aspirin may decompose (hydrolysis) into salicylic acid and acetic acid. This reaction is the reverse of the synthesis reaction. The maximum allowable amount of free salicylic acid in an aspirin sample is 0.15% salicylic acid. 1.
How much acetylsalicylic acid is in aspirin?
Each tablet contains 75 mg acetylsalicylic acid. For the full list of excipients, see section 6.1.

What is the AHFS Drug Information for aspirin?
AHFS Drug Information. American Society of Health-System Pharmacists, Bethesda, MD. 2007., p. 2037 CHEMICAL PROFILE: Aspirin. Almost all aspirin manufactured in the US is used in aspirin tablets, pharmaceutical products or in conjunction with other ingredients for its analgesic and antipyretic properties.
What are the physical properties of aspirin?
Physical properties Aspirin, an acetyl derivative of salicylic acid, is a white, crystalline, weakly acidic substance, with a melting point of 136 °C (277 °F), and a boiling point of 140 °C (284 °F). Its acid dissociation constant (p Ka) is 3.5 at 25 °C (77 °F).
What is the stability of aspirin at different pHs?
In aqueous solutions, aspirin is most stable at a pH of 2-3, less stable at a pH of 4-8, and least stable at a pH less than 2 or greater than 8. In a saturated aqueous solution at a pH of 5-7, aspirin is almost completely hydrolyzed within 1 week at 25 °C.
