Water solubility: M-e-t-h-a-n-o-l (Slightly), Water (Slightly)

Storage conditions: -20 ° C Freezer, Under inert atmosphere

Refractive index: 1.811

Physical and chemical properties: It appears rose red in aqueous solutions with pH<3, slightly purple in aqueous solutions with pH=3, and turns purple when pH>4. It appears light green in concentrated sulfuric acid. Decompose in concentrated n-i-t-r-i-c acid. It appears light blue in s-o-d-i-u-m h-y-d-r-o-x-i-d-e and sodium carbonate solutions. The molar absorption coefficient ranges from 74500 to 75500, indicating higher complexation performance than a-r-s-i-n-e azo I.

Product use: Chlorophosphonazo III is a reagent sensitive to both calcium and magnesium. Calcium can be measured separately at pH 2.2, and calcium and magnesium can be measured at pH 7.0. Chlorophosphonazo III can also be used for spectrophotometric determination of titanium, zirconium, thorium, scandium, pentavalent actinide elements, and rhenium.
