4-amino-1-ethyl-1H-pyrazole-5-carboxamide - Introduction
Acid amide is an organic compound whose molecular formula is C7H11N5O. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
-Appearance: acid amide is a white crystalline solid.
-Melting point: The melting point of the compound ranges from 132 to 135°C.
-Solubility: It has limited solubility in water and is soluble in hot acidic solution.
Use:
Acid amide is mainly used in organic synthesis reactions, for example, as a pharmaceutical intermediate or a raw material for the synthesis of dye compounds. It is also used as a ligand or complexing agent in coordination chemical reactions.
Preparation Method:
The preparation method of acid amide can be achieved through the following steps:
1. First, 2-acetyl acetone and diethyl oxalic anhydride are reacted to generate 2-acetyl -1,3-diethyl urea.
2. Next, the above product is reacted with sodium hypochlorite to produce 4-amino-2-ethyl-2H-pyrazole-3-carboxylic acid.
3. finally, 4-amino -2-ethyl-2H-pyrazole-3-carboxylic acid is reacted with the corresponding acid chloride to generate acid amide.
Safety information: Currently, there is limited toxicity data for acidamide, so use appropriate safety precautions, such as wearing gloves, goggles and laboratory coats. At the same time, care must be taken to avoid contact with the skin and eyes, to avoid inhalation of its dust or vapor. In case of accidental contact, rinse immediately with plenty of water and seek medical attention.
