Background:

Cacodylic acid has been widely used in buffers for electron microscopy techniques.¹It has also been used to introduce arsenic into proteins for single-wavelength anomalous diffraction (SAD) phasing in protein crystallography.²Cacodylic acid has also been used as an herbicide, acting as a defoliant.³In rats exposed to carcinogens, cacodylic acid increases the likelihood of tumor formation in the bladder, kidney, liver, and thyroid gland at concentrations as low as 50 ppm for the bladder.⁴
