Description

General description

Sodium cacodylate is an organic arsenic compound that is metabolized to produce inorganic, trivalent arsenic in vivo. Sodium cacodylate has been used as a source of arsenic in toxicological research. It is used as a buffer with an effective pH buffering range of 5.1-7.4. In microscopy studies, the buffering capacity of cacodylate prevents excess acidity that may result from tissue fixation.

Application

Sodium cacodylate trihydrate has been used in the stabilization of the fixatives for electron microscopy. It has also been used to collect vibratome sections to perform nucleoside-diphosphatase technique.

Packaging

10, 25, 100, 500 g in poly bottle
