Description

Sodium Hydrogen Ferric Dtpa CAS NO 12389-75-2 is a high-purity, water-soluble chelating agent complex of iron (Fe³⁺) with diethylenetriaminepentaacetic acid (DTPA). This compound is engineered for superior stability and bioavailability, making it an essential component in formulations requiring controlled iron delivery. It is primarily utilized by manufacturers in the agricultural, pharmaceutical, and industrial water treatment sectors for its effective chelation properties.

Application

• Agricultural Micronutrient Fertilizers: As a highly effective source of plant-available iron in chelated foliar sprays and hydroponic nutrient solutions to correct chlorosis.
• Pharmaceutical & Nutraceutical Ingredients: Used in the formulation of iron supplements and mineral fortification due to its high bioavailability and gastrointestinal tolerance.
• Industrial Water Treatment: Acts as a scale and corrosion inhibitor in boiler and cooling water systems by sequestering metal ions.
• Chemical Synthesis & Catalysis: Serves as a precursor or catalyst in specialized organic synthesis and oxidation reactions.
• Pulp & Paper Processing: Utilized in bleaching processes to stabilize peroxides and improve brightness by controlling transition metal ions.
• Textile & Dyeing Auxiliary: Functions as a chelating agent to prevent metal-ion interference during dyeing and finishing processes.

Quality Control

Our Sodium Hydrogen Ferric Dtpa is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for iron content, chelation efficiency, and purity. A Certificate of Analysis (COA) documenting identity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
