HEPES Chemical Properties,Uses,Production

Chemical Properties

White crystalline powder

Uses

Non-toxic to cell. It is used as a hydrogen ion buffer, which can control the constant pH range for long term. The concentration is 10-50mmol/L. Generally, 20mmol/LHEPES in nutrient solution can get buffer ability.

Uses

Biological buffer.

Definition

ChEBI: A HEPES that is ethanesulfonate substituted by a 4-(2-hydroxyethyl)piperazin-4-ium-1-yl group at position 2.

Biological Activity

Multi purpose buffer used in biological research.

Purification Methods

Crystallise the acid from hot EtOH and water. It is a useful buffer. [Beilstein 23 V 376.]
