Beryllon II 

Beryllon II is a widely used chromogenic reagent that is used to determine many elements, such as Mo, Mg and Co, and also used for the determination of proteins.

Beryllon II is a widely used chromogenic reagent that has been used to determine many elements, such as Mo, Mg and Co. Beryllon II-Al³⁺ complex with the addition of protein can potently enhance the Rayleigh light scattering, and used to determine proteins^[1].
