Is aspirin an acetyl ester?
Is aspirin an acetyl ester?
Aspirin is a trade name for acetylsalicylic acid, a common analgesic. Acetylsalicylic acid is an acetic acid ester derivative of salicylic acid.
Does ASA have an acetyl group?
The acetyl group of acetylsalicylic acid binds with a serine residue of the cyclooxygenase-1 (COX-1) enzyme, leading to irreversible inhibition. This prevents the production of pain-causing prostaglandins.
What is role of acetyl chloride in aspirin preparation?
Acetyl chloride is a very reactive compound. Acetyl chloride reacts with Salicylic acid vigorously in the presence of pyridine to form acetylsalicylic acid or the aspirin . Aspirin can also be formed by the reaction of salicylic acid and acetic anhydride.
Does aspirin contain COOH group?
The common name of aspirin is acetylsalicylic acid and its IUPAC name is 2-Acetoxybenzoic acid. Between ester and carboxylic acid functional groups the highest priority functional group is carboxylic acid. Hence, in aspirin carboxylic acid is the principal functional group. Therefore, the correct option is B, -COOH.
Why is aspirin an ester?
Salicylic acid is treated with acetic anhydride, an acid derivative, causing a chemical reaction that turns salicylic acid’s hydroxyl group into an ester group (R-OH → R-OCOCH3). This process yields aspirin and acetic acid, which is considered a byproduct of this reaction.
What is aspirin Chem?
The Chemistry of Aspirin (acetylsalicylic acid) Chemical formula = C9H8O4 or CH3COOC6H4COOH or HC9H7O4. Aspirin is prepared by chemical synthesis from salicylic acid, through acetylation with acetic anhydride. The molecular weight of aspirin is 180.16g/mol.
What class of organic compound is aspirin?
acylsalicylic acids
Aspirin, also known as acetylsalicylate or easprin, belongs to the class of organic compounds known as acylsalicylic acids. These are o-acylated derivatives of salicylic acid.
Is acetyl chloride an ester?
Acetyl chloride is a reagent for the preparation of esters and amides of acetic acid, used in the derivatization of alcohols and amines. One class of acetylation reactions are esterification.
