      • Overview
        • XB-I is a colorimetric reagent for Mg detection. It is slightly soluble in water and alcohol, and readily soluble in aqueous alkaline solution. The aqueous solution of XB-1 is red, and turns reddish-violet in the presence of Mg at pH 9 (maximum wavelength: 510 nm, molar absorptivity: 49,000, detection range 0.02-0.4 ppm).
