What is the structural formula of aspirin?
C₉H₈O₄Aspirin / Formula
What kind of structure is aspirin?
Aspirin Formula and Structure The chemical formula for Acetylsalicylic Acid is C9H8O4. Similarly, the extended formula for the same is said to be CH3COOC6H4COOH. Further, the molecular mass of it is around 180.159 g mol-1.
What is the balanced equation for the synthesis of aspirin?
*The chemical equation corresponding to the synthesis reaction is: C7H6O3 + (CH3CO)2O → C9H804 + CH3COOH.
Is Asa aspirin?
ASA is short for acetylsalicylic acid, which is sold under names including Aspirin, Entrophen and Novasen.
What does aspirin stand for?
1899: Acetylsalicyclic acid is named Aspirin by Bayer. The letter ‘A’ stands for acetyl, “spir” is derived from the plant known as Spiraea ulmaria (meadowsweet), which yields salicin, and “in” was a common suffix used for drugs at the time of the first stable synthesis of acetylsalicylic acid.
What is the chemical reaction of aspirin?
Aspirin, acetylsalicylic acid (3.2. 2), is synthesized by the acetylation of salicylic acid (3.2. 1) using acetic anhydride or acetyl chloride [60–63]. Aspirin exhibits analgesic, fever-reducing, and anti-inflammatory action, and it also reduces aggregation of thrombocytes.
Is aspirin an ester?
Background. Aspirin is a trade name for acetylsalicylic acid, a common analgesic. Acetylsalicylic acid is an acetic acid ester derivative of salicylic acid.
Is aspirin and ASA the same?
Why is aspirin called aspirin?
What is an aspirin made of?
Aspirin is prepared by chemical synthesis from salicylic acid, through acetylation with acetic anhydride. The molecular weight of aspirin is 180.16g/mol. It is odourless, colourless to white crystals or crystalline powder.
Why is aspirin ester?
The preparation consists of an esterification reaction catalyzed by acid (H2SO4 or H3PO4), where salicylic acid treated with acetic anhydride gives acetylsalicylic acid (aspirin). In this reaction, a hydroxyl group is converted to an ester, with acetic acid as a byproduct.
Why does ASA stand for aspirin?
Who invented aspirin?
In 1897, Felix Hoffman, a German chemist working for the Bayer company, was able to modify salicylic acid to create acetylsalicylic acid, which was named aspirin (Fig. 1).
