Description

Sodium 2,9-Dimethyl-4,7-Diphenyl-1,10-Phenanthrolinesulphonate is a high-purity, water-soluble derivative of bathophenanthroline, a classic chelating agent and chromogenic reagent. This compound is valued for its exceptional selectivity and sensitivity as a spectrophotometric reagent for the determination of trace metal ions, particularly iron(II). It is essential for analytical chemists and quality control laboratories in industries requiring precise metal quantification, such as pharmaceuticals, environmental monitoring, and high-purity material manufacturing.

Application

• Spectrophotometric Analysis: Primary use as a highly sensitive and selective colorimetric reagent for the detection and quantification of iron (Fe²⁺) in various matrices.
• Pharmaceutical QC: Used in the analysis of active pharmaceutical ingredients (APIs), excipients, and finished drug products for trace metal impurities to ensure compliance with pharmacopeial limits (e.g., USP, EP).
• Environmental Testing: Employed in water and soil analysis to monitor iron levels and other chelatable metals for environmental safety and regulatory compliance.
• Food & Beverage Industry: Applied in the analysis of food products, beverages, and nutritional supplements for essential and contaminant metal content.
• Chemical Research & Development: Serves as a key reagent in developing new analytical methods, studying metal-ligand interactions, and in supramolecular chemistry.
• High-Purity Material Production: Used in the quality control of semiconductors, catalysts, and other advanced materials where trace metal content is critical.
• Clinical Diagnostics: Potential use in vitro diagnostic kits for measuring serum iron or other metal ions.

Quality Control

Our Sodium 2,9-Dimethyl-4,7-Diphenyl-1,10-Phenanthrolinesulphonate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometric verification of performance, and tests for residual solvents and moisture. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring traceability and compliance with your methodological and regulatory requirements.

Storage

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