English name: Chlorophosphonazo I

Molecular formula: C10H6ClN2O7P

Molecular weight: 538.819

IUPAC name: 3- ((4-chloro-2-phosphonylphenyl) hydrazide) -5-hydroxy-4-oxonaphthalene-2,7-disulfonic acid

2. Physical and chemical properties:

Dark red crystalline powder, easily soluble in water.

3. Purpose:

Mainly used in the field of analytical chemistry, it is a commonly used analytical reagent that can be used to determine various metal ions, such as rare earth elements, calcium, magnesium, etc. After color reaction with metal ions, quantitative analysis can be carried out through colorimetric methods and other means.

Photometric analysis: commonly used for the determination of the total amount of rare earth elements. Under certain conditions, chlorophosphonazo I can form a stable colored complex with rare earth elements. By measuring the absorbance of the complex at a specific wavelength, quantitative analysis of the content of rare earth elements can be achieved. It can also be used to determine elements such as thorium and uranium, and has important applications in the analysis of geological samples, nuclear fuels, and other fields.

Research field: As a metal ion chromogenic agent, it can be used to study basic chemical problems such as the interaction mechanism between metal ions and organic reagents, the structure and stability of complexes. In the study of the chemical properties and biological activities of rare earth elements, chlorophosphonazo I can also serve as an important research tool for tracking and analyzing the behavior of rare earth ions in chemical reactions and biological systems.

Storage conditions: Generally, it should be sealed and stored in a cool, dry place, away from direct sunlight.
