CUPRAL - Introduction
It's hygroscopic. The aqueous solution was alkaline and gradually separated. In case of acid, carbon disulfide can be separated to make the solution cloudy. The maximum absorption wavelength (in ethanol) is 257 and 290nm (molar absorption coefficient is 1200 and 13000). Low toxicity, half lethal dose (rat, oral).
