[2H]formic [2]acid - Introduction
[2H] ic [2]acid is a deuterated formic acid with the chemical formula DCOOH. The following is an introduction to the nature, use, preparation and safety information of [2H]formic [2]acid:
Nature:
- [2H] formal [2]acid is a colorless liquid with a pungent odor.
-its density and boiling point is slightly higher than ordinary formic acid.
- [2H] formal [2]acid is soluble in water and most organic solvents at room temperature.
-It is a medium strong acid that can react with alkali to form formate.
Use:
- [2H] formal [2]acid is mainly used as a labeling reagent in the laboratory to study the mechanism and kinetics of chemical reactions.
-Because the deuterium atom in [2H] formal [2]acid has a larger atomic mass than ordinary hydrogen atoms, it can be used to label molecules in deuterated reaction studies and nuclear magnetic resonance (NMR) experiments.
Method: The preparation method of
[2H] formal [2]acid includes the following steps:
1. Sodium deuterium oxide (NaOD) reacts with sulfur dioxide (SO2) to generate DeSO2 (sodium deuterated sulfite).
2. Heat and react DeSO2 with methanol (CH3OD) to generate [2H] formal [2]acid.
[2H] formal [2] The preparation of acid needs to be carried out under specific conditions. For non-professionals, it is best to buy from a reliable chemical supplier.
Safety Information:
- [2H] formal [2]acid has a pungent odor, and care should be taken to avoid inhaling its vapor.
-Wear appropriate protective gloves and glasses during use to avoid contact with skin and eyes.
-Avoid contact with strong oxidants and acidic substances to avoid dangerous reactions.
-Keep away from fire and high temperature during use and storage.
- [2H] formal [2]acid should be properly stored to avoid prolonged exposure to the air to prevent oxidative decomposition.
Please note that [2H] formal [2]acid is a chemical reagent, and safe operating procedures should be followed during operation, and proper handling should be carried out according to specific conditions. If necessary, please operate under the guidance of professionals.
