N-Cyclohexyl-2-aminoethanesulfonic acid, also known as CHES, is a buffering agent.

Typically appears as a white crystalline powder.

Decomposition or burning may produce toxic fumes such as carbon monoxide, carbon dioxide, nitrogen oxides and sulfur oxides.

CHES buffers have a useful range of pH 8.6–10.
