CAS 1466-82-6

Acetylsalicylic anhydride

Description:

Acetylsalicylic anhydride, with the CAS number 1466-82-6, is a chemical compound derived from acetylsalicylic acid, commonly known as aspirin. It is characterized by its anhydride functional group, which is formed by the dehydration of two acetylsalicylic acid molecules. This compound typically appears as a white to off-white solid and is known for its reactivity, particularly in hydrolysis reactions where it can revert to acetylsalicylic acid in the presence of moisture. Acetylsalicylic anhydride is primarily used in organic synthesis and as an intermediate in the production of various pharmaceuticals. Its properties include moderate solubility in organic solvents and limited solubility in water. Due to its chemical structure, it can exhibit both acidic and basic characteristics, making it useful in various chemical reactions. Safety precautions should be taken when handling this compound, as it can be irritant and may pose health risks if inhaled or ingested.

Aspirin Impurity F

CAS: 1466-82-6

Aspirin Impurity F is a by-product of the acetylation reaction that occurs when aspirin is synthesized. It is also a by-product of hydrochloric acid and anhydrous sodium reacting with solanum tuberosum, which is the plant from which aspirin is extracted. Aspirin Impurity F can cause allergic reactions in some people who are sensitive to aspirin or acetylsalicylic acid.
