Description

Ferrozine Disodium Salt is a high-purity, water-soluble chelating agent specifically designed for the sensitive and selective colorimetric detection of ferrous ions (Fe²⁺). Its core value proposition lies in forming a stable, intensely colored magenta complex with Fe²⁺, enabling precise quantitative analysis across various scientific and industrial fields. This reagent is essential for researchers and quality control laboratories in sectors such as pharmaceutical manufacturing, environmental monitoring, clinical diagnostics, and food & beverage analysis, where accurate iron quantification is critical.

Application

• Spectrophotometric Iron Assays: Primary reagent for quantifying ferrous iron in water, wastewater, and environmental samples.
• Pharmaceutical Quality Control: Used in testing raw materials, drug substances, and finished products for iron content as per pharmacopeial methods.
• Clinical & Biochemical Research: Determination of non-heme iron in biological fluids, cell cultures, and tissue homogenates.
• Food & Beverage Analysis: Monitoring iron fortification levels and detecting trace iron contamination in products.
• Industrial Process Control: Monitoring iron ions in chemical processes, boiler feed water, and high-purity chemical production.
• Method Development & Validation: Serves as a key component in developing and validating new analytical protocols for metal detection.

Quality Control

Our Ferrozine Disodium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure high purity, consistent performance, and compliance with relevant analytical reagent standards. Key parameters including assay, absorbance characteristics, and impurity profiles are verified. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent absorption of atmospheric moisture, which can affect performance and stability.
