Cacodylic acid is an organoarsenic compound with the formula (CH3)2AsO2H. With the formula R2As(O)OH, it is the simplest of the arsinic acids. It is a colorless solid that is soluble in water. Neutralization of cacodylic acid with base gives cacodylate salts, e.g. sodium cacodylate. They are potent herbicides. Cacodylic acid/sodium cacodylate is a buffering agent in the preparation and fixation of biological samples for electron microscopy and in protein crystallography.

Roles Classification
Biological Role(s): alpha-adrenergic antagonist
An agent that binds to but does not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous alpha-adrenergic agonists. alpha-Adrenergic antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma.
EC 3.4.21.26 (prolyl oligopeptidase) inhibitor
Any EC 3.4.21.* (serine endopeptidase) inhibitor that interferes with the action of prolyl oligopeptidase (EC 3.4.21.26).
Application(s): antihypertensive agent
Any drug used in the treatment of acute or chronic vascular hypertension regardless of pharmacological mechanism.
alpha-adrenergic antagonist
An agent that binds to but does not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous alpha-adrenergic agonists. alpha-Adrenergic antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma.
