Properties and stability
Avoid contact with oxides.
Storage method
1. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. They should be stored separately from oxidants, etc. and avoid mixed storage. 2. Equip with corresponding varieties and quantities of fire-fighting equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.
Synthesis method
1. Dissolve pyruvic acid in water, add sodium hydroxide for neutralization reaction, add ethanol to precipitate acetone Sodium acid crystals.
2.tartaric acid can remove its carboxyl group under the action of potassium hydrogen sulfate to obtain pyruvic acid:
Dissolve pyruvic acid in water, neutralize it with sodium hydroxide, and then use ethanol to precipitate its sodium salt crystal.
Purpose
1. Determine the substrate of lactate dehydrogenase. Determination of alanine aminotransferase activity in liver function tests.
2. Biochemical reagents. A reagent for measuring the content of glutamic-alanine aminotransferase or glutamic-grass aminotransferase in human blood.
3.Used as a biochemical analysis reagent to determine the G.P.T or G.O.T content in human blood.
