Chemical Property/Description
Its physical and chemical properties are as follows: dark purple powder. Soluble in water, slightly soluble in ethanol, Insoluble in benzene and other general organic solvents. Blue in strong inorganic acids. Chemicalbook generally appears in the acidic medium blue purple. When pH = 4, it appears rose red and can form water-soluble blue complexes with calcium and titanium ions. Easy to be destroyed by strong oxidant or strong reducing agent.


Main Uses:
In the current environmental protection industry requirements, in the process of environmental testing, environmental monitoring and environmental governance, especially in the process of water quality testing and governance, the analysis of calcium is very important. As a new type of high sensitivity display agent, m-formylchlorophosphine azo has the characteristics of rapid, efficient, accurate and simple.  Chlorophosphonazo I is the raw material for the synthesis of m-formylchlorophosphine azo.
