Description

Disodium 4,4'-(2,9-Dimethyl-1,10-Phenanthroline-4,7-Diyl)Bis(Benzenesulphonate) is a high-purity, water-soluble phenanthroline derivative that serves as a critical chelating agent and chromogenic reagent. Its primary value lies in its ability to form stable, intensely colored complexes with various metal ions, enabling highly sensitive detection and quantification. This compound is essential for researchers and quality control laboratories in the pharmaceutical, analytical chemistry, and environmental monitoring sectors.

Application

• Spectrophotometric Reagent: Used as a sensitive colorimetric indicator for the detection and quantification of trace metal ions, particularly iron (Fe²⁺/Fe³⁺), copper (Cu²⁺), and other transition metals in analytical chemistry.
• Pharmaceutical Analysis: Employed in the development and validation of analytical methods for drug substances and finished products, especially for metal impurity testing and assay development.
• Environmental Testing: Applied in water and soil analysis kits and laboratory procedures to monitor heavy metal contamination and assess environmental quality.
• Biochemical Research: Functions as a selective chelator in biochemical assays to study metal-dependent enzyme activity, protein function, and cellular metal homeostasis.
• Dye & Pigment Intermediate: Serves as a precursor or complexing agent in the synthesis of specialized dyes, pigments, and functional materials due to its chromophoric properties.
• Catalysis Research: Utilized as a ligand to prepare homogeneous catalysts for organic synthesis and oxidation reactions, leveraging its strong metal-binding affinity.
