Descrição geral

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.[1] 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.[2][3]

Aplicação

Sodium cacodylate trihydrate has been used in the stabilization of the fixatives for electron microscopy.[4] It has also been used to collect vibratome sections to perform nucleoside-diphosphatase technique.[5]
