Chlorophosphonazo III

Description:

Chlorophosphonazo III is a synthetic organic compound that belongs to the class of azo dyes, characterized by the presence of azo (-N=N-) functional groups. It is primarily used as a colorimetric reagent in analytical chemistry, particularly for the detection and quantification of metal ions. The compound exhibits a vivid color, which is a hallmark of azo dyes, allowing for visual identification and spectrophotometric analysis. Chlorophosphonazo III is soluble in organic solvents and has limited solubility in water, making it suitable for various applications in both aqueous and non-aqueous environments. Its structure typically includes chlorinated aromatic rings, contributing to its stability and reactivity. The compound is known for its ability to form stable complexes with transition metals, which is essential for its role in analytical methods. Safety considerations should be taken into account when handling this substance, as azo dyes can pose environmental and health risks. Proper laboratory practices and disposal methods are recommended to mitigate any potential hazards associated with its use.

Chlorophosphonazo III

CAS: 1914-99-4

Chlorophosphonazo III is a malonic acid derivative. It reacts with hydrochloric acid in the presence of an optical sensor to form a reaction solution that can be analyzed by plasma mass spectrometry. Chlorophosphonazo III has been used as a diagnostic agent and as a physiological activity indicator for damaged tissue, such as adhesions. This compound is also acidic, so it should not be stored in contact with human serum or other biological fluids because it will react with them.
