Product Description

Shandong Believe Chemical Pte. Ltd. HEPES CAS 7365-45-9 is an important hydrogen ion buffer. 

It has a good buffering capacity in the range of pH 6.8-8.2, and can control a constant chemical Book pH for a long time. When the concentration is 10-50mmol / L, the general culture medium containing 20mmol / L 4-hydroxyethyl piperazine ethanesulfonic acid can have good buffering capacity and has no toxic effect on cells.

Preparation method:

 directly use 1,2-dichloroethane as solvent, add hydroxyethyl piperazine (5.00g, 0.02mol), potassium carbonate K2CO3 (6.00g, 0.04mol), 50ml1,2-chemicalbook dichloroethane into a 100ml three mouth bottle equipped with mechanical stirring and thermometer, heat the oil bath at 90 ° C (boiling point of 1,2-dichloroethane: 85 ° C), and stir for 20h. 

The reaction was stopped, filtered, and the filtered salt was washed with 200 ml of ethyl acetate (EA). The filtrate was spin dried to obtain 2.6 g of HEPES (4-hydroxyethyl piperazine ethanesulfonic acid) as a solid.
