Description

Cadion 2B is a high-purity analytical reagent widely used as a sensitive and selective chromogenic agent for the detection and quantification of trace metals. Its primary value lies in forming intensely colored, stable complexes with specific metal ions, enabling precise colorimetric analysis in various matrices. This compound is essential for quality control laboratories and research institutions in the chemical, pharmaceutical, and environmental monitoring sectors.

Application

• Spectrophotometric Analysis: Primary use as a chromogenic reagent for the colorimetric determination of cadmium, nickel, and other heavy metal ions in solution.
• Environmental Testing: Detection and measurement of trace metal contaminants in water, soil, and industrial effluent samples.
• Pharmaceutical QC: Analysis of catalyst residues or metal impurities in active pharmaceutical ingredients (APIs) and excipients.
• Industrial Chemistry: Process control and quality assurance in metal plating, alloy production, and catalyst manufacturing.
• Research & Development: Used in academic and industrial R&D for developing new analytical methods and studying metal-ligand interactions.
• Food Safety: Potential application in screening for heavy metal contamination in food products and additives.

Quality Control

Our Cadion 2B is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including identification (IR), purity assay (HPLC), and loss on drying, to ensure it meets the high standards required for analytical reagent applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with specified parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after use to prevent moisture absorption, which can affect performance and stability.
