Description

Ferene Disodium Salt is a high-purity, water-soluble iron chelator and chromogenic reagent widely used in analytical chemistry. Its primary value lies in its exceptional sensitivity and selectivity for iron(II) ions, forming a stable, intensely colored complex ideal for quantitative spectrophotometric analysis. This compound is essential for industrial and research laboratories requiring precise iron quantification, particularly in water quality testing, pharmaceutical raw material analysis, and biochemical research. Its disodium salt form ensures excellent solubility and stability in aqueous solutions, making it a reliable component in diagnostic kits and standardized test methods.

Application

• Spectrophotometric Iron Assay: Primary reagent for the sensitive colorimetric detection and quantification of ferrous (Fe²⁺) ions in solution.
• Water and Environmental Analysis: Used in test kits and laboratory procedures to measure trace iron levels in drinking water, wastewater, and environmental samples.
• Pharmaceutical Quality Control: Employed in the analysis of active pharmaceutical ingredients (APIs) and excipients for iron impurity content.
• Clinical and Biochemical Research: Serves as a key component in assays studying iron metabolism, chelation therapy, and related biochemical pathways.
• Industrial Process Monitoring: Applied for monitoring iron concentrations in chemical manufacturing, food processing, and metal treatment baths.
• Diagnostic Reagent Formulation: Incorporated into ready-to-use liquid and dry-powder reagent formulations for clinical and industrial analyzers.

Quality Control

Our Ferene Disodium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, spectrophotometric verification of chromogenic activity, and tests for heavy metals and residual solvents. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and performance characteristics is provided with every shipment to ensure it meets the stringent requirements of analytical and diagnostic applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the original container tightly sealed in a dry environment to prevent absorption of atmospheric moisture, which can affect performance and stability.
