Description

Diethylenetriaminepentaacetic Acid (DTPA) is a powerful, high-affinity chelating agent belonging to the aminopolycarboxylic acid family. Its primary value lies in its exceptional ability to sequester and deactivate di- and trivalent metal ions, even under challenging conditions. This versatile compound is essential for industries requiring precise metal ion control, water treatment, and advanced material synthesis.

Application

• Industrial Water Treatment: Used as a scale and corrosion inhibitor in boiler and cooling water systems by chelating calcium, magnesium, and iron ions.
• Pulp & Paper Manufacturing: Serves as a chelant in bleaching processes to deactivate transition metal ions that catalyze pulp degradation.
• Textile Processing: Acts as a sequestrant to prevent metal-ion interference during dyeing and bleaching operations, ensuring color consistency.
• Agricultural Chemicals: Incorporated into micronutrient fertilizers and agrochemical formulations to improve nutrient stability and bioavailability.
• Chemical Synthesis & Catalysis: Employed as a ligand in coordination chemistry and to stabilize metal catalysts in various organic reactions.
• Detergent & Cleaning Formulations: Functions as a builder to soften water and enhance the cleaning efficiency of surfactants.
• Radiopharmaceuticals: Forms stable complexes with radioactive metal isotopes (e.g., Technetium-99m, Indium-111) for diagnostic imaging.
• Analytical Chemistry: Used as a masking agent in titrations and other analytical procedures to eliminate interference from specific metal ions.

Quality Control

Our Diethylenetriaminepentaacetic Acid is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets the required specifications for industrial and technical applications. Certificates of Analysis (COA) are provided to guarantee traceability, purity, and batch-to-batch consistency.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can lead to caking or degradation.
