CAS 123-62-6

Propionic anhydride

Description:

Propionic anhydride, with the CAS number 123-62-6, is an organic compound characterized by its anhydride functional group derived from propionic acid. It appears as a colorless to pale yellow liquid with a pungent odor. The compound is known for its reactivity, particularly in acylation reactions, where it can introduce propionyl groups into various substrates. Propionic anhydride is soluble in organic solvents such as ether and chloroform but is not miscible with water due to its hydrophobic nature. It has a relatively low boiling point, making it volatile. This substance is primarily used in the synthesis of propionates and as a reagent in organic chemistry for the preparation of esters and amides. However, it is important to handle propionic anhydride with care, as it can be corrosive and may cause irritation to the skin, eyes, and respiratory system. Proper safety precautions, including the use of personal protective equipment, are essential when working with this chemical.

Controlled Product

CAS: 123-62-6

Propionic anhydride is a reactive, stable complex that can be used for sample preparation. It has been shown to be an effective reagent for the conversion of crystalline cellulose to cellobiose. Propionic anhydride is also used in the preparation of a wide variety of organic compounds, such as trifluoroacetic acid and its derivatives. In the laboratory, propionic anhydride is most commonly used in the preparation of analytical methods for alkanoic acids. The thermal expansion and water vapor are both high, with values of 5.1x10-5 and 5.3x10-5 mK-1 respectively. The boiling point is at 138 degrees Celsius, which makes it ideal for use in organic synthesis reactions that require heating or boiling.
