-acetic anhydride - Introduction
(Acetic anhydride)-d6 (also known as Acetic anhydride-d6) is a heavy-labeled compound containing six deuterium atoms, with the chemical formula (CH3COOD) or (CD3COOD). The following is an introduction to the nature, use, preparation and safety information of (Acetic anhydride)-d6:
Nature:
- (Acetic anhydride)-d6 is a colorless liquid, odorless at room temperature.
-It has a higher density, with a melting point of -78°C and a boiling point of 83°C.
- (Acetic anhydride)-d6 is soluble in most organic solvents such as ethanol, ethers and hydrocarbons.
-It is stable and not prone to decomposition or reaction.
Use:
- (Acetic anhydride)-d6 is widely used as a re-labeling reagent in nuclear magnetic resonance (NMR) spectroscopy studies.
-It is often used as a deuterium source and a solvent for esterification reactions in organic synthesis.
- (Acetic anhydride)-d6 can be used to analyze and study the structure and reaction mechanism of organic compounds.
Method:
- (Acetic anhydride)-d6 can be obtained by reacting Acetic acid-d6 with an acid catalyst (such as sulfuric acid). This reaction will cause the esterification of Acetic acid-d6 to produce (Acetic anhydride)-D6.
-It should be noted that the reaction should be carried out under strictly anhydrous conditions to avoid water interference.
Safety Information:
- (Acetic anhydride)-d6 is generally considered to be relatively safe, but it is still necessary to pay attention to follow laboratory safety procedures during use.
-Its vapor may cause irritation to the eyes, skin and respiratory system, so use it to avoid inhalation of vapor or contact with skin. Appropriate personal protective equipment such as gloves, goggles and laboratory coats should be worn.
-When handling (Acetic anhydride)-d6, it should be stored in a sealed container, away from fire and oxidizing agents. When abandoning, please follow the relevant local regulations.
