Cacodylic acid presents as a crystalline powder, varying from white to brown, and demonstrates solubility in water, alcohols, and acetic acid, but lacks solubility in ether. It is uses as an analytical reagent, it serves to inhibit polymerase chain reaction (PCR). Recognized as a mild arsenic acid, cacodylic acid can undergo exothermic oxidation when introduced to potent oxidizing agents and can be reduced by powerful reducing agents. Cacodylic acid is a useful arsinic acid for proteomics research.
