Description

Ferrozine Sodium is a highly specific and sensitive chromogenic reagent widely used for the quantitative determination of iron ions. Its core value lies in forming a stable, intensely colored magenta complex with ferrous iron (Fe²⁺), enabling precise colorimetric analysis. This compound is essential for researchers and quality control laboratories requiring accurate iron quantification. Key industries that rely on this reagent include pharmaceutical manufacturing, environmental monitoring, clinical diagnostics, and food & beverage analysis.

Application

• Spectrophotometric Iron Assays: Primary reagent for the quantitative colorimetric determination of ferrous iron (Fe²⁺) in solution.
• Pharmaceutical Quality Control: Used in testing raw materials, active pharmaceutical ingredients (APIs), and finished drug products for iron content to ensure purity and safety.
• Environmental & Water Analysis: Detection and measurement of trace iron levels in drinking water, wastewater, and environmental samples.
• Clinical & Diagnostic Reagents: A key component in diagnostic kits and laboratory tests for measuring serum iron, total iron-binding capacity (TIBC), and related parameters.
• Food & Beverage Industry: Analysis of iron fortification levels and monitoring of iron content in products like infant formula, cereals, and beverages.
• Biochemical & Cell Culture Research: Used in studies of iron metabolism, cellular iron uptake, and as an indicator in cell culture media analysis.
• Industrial Process Control: Monitoring iron contamination or specific iron species in chemical manufacturing, semiconductor production, and metal treatment baths.

Quality Control

Our Ferrozine Sodium is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity, consistent performance, and compliance with relevant industry standards for analytical reagents. A comprehensive Certificate of Analysis (COA) detailing identity, purity, assay, and impurity profiles 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a low-humidity environment to prevent degradation and ensure long-term stability.
