Sodium cacodylate trihydrate

Description:
Sodium cacodylate trihydrate is an organoarsenic compound with the chemical formula C2H6AsNaO3S·3H2O. It appears as a white crystalline solid and is commonly used as a buffering agent in biological and biochemical research, particularly in electron microscopy and tissue preservation. The compound is soluble in water, which facilitates its use in various aqueous solutions. Sodium cacodylate trihydrate is known for its ability to maintain a stable pH in biological systems, making it valuable in experiments that require precise pH control. However, due to the presence of arsenic, it is important to handle this compound with caution, as arsenic is toxic and poses health risks. Safety measures should be taken to avoid inhalation or skin contact. In terms of stability, sodium cacodylate trihydrate is generally stable under normal conditions, but it should be stored in a cool, dry place away from incompatible substances.
