Description

Zincon CAS NO 59600-76-9 is a high-purity, heterocyclic organic compound widely recognized as a highly selective chromogenic reagent for the detection and quantification of zinc and copper ions. Its core value lies in forming stable, intensely colored complexes with these metal ions, enabling precise analytical measurements in complex matrices. This product is essential for professionals in analytical chemistry, environmental monitoring, and industrial process control who require reliable and sensitive metal ion analysis.

Application

• Spectrophotometric Analysis: Primary use as a colorimetric reagent for the quantitative determination of zinc (Zn²⁺) and copper (Cu²⁺) ions in solution.
• Environmental Testing: Detection of trace heavy metals in water, wastewater, and soil samples for environmental compliance and safety monitoring.
• Biological & Clinical Research: Used in assays to study zinc and copper homeostasis, metalloprotein function, and related biochemical pathways.
• Industrial Quality Control: Monitoring metal ion concentrations in electroplating baths, alloy production, and catalyst formulations.
• Educational & Laboratory Use: A standard reagent in university and research laboratory curricula for teaching complexometric titration and spectroscopic methods.
• Reagent Manufacturing: Serves as a key raw material in the formulation of proprietary test kits and diagnostic strips for metal detection.
