Description

Cdta Sodium Salt, Dcta Sodium Salt, 1,2-Diaminocyclohexanetetraacetic Acid Solution Tetrasodium Salt is a high-purity, water-soluble chelating agent belonging to the polyaminocarboxylic acid family. It is valued for its strong and selective complexing ability with di- and trivalent metal ions, particularly calcium and magnesium, under a wide range of pH conditions. This product is essential for industries requiring precise metal ion control, such as pharmaceutical manufacturing, analytical chemistry, and detergent formulation.

Application

• Pharmaceutical & Cosmetic Ingredient: Used as a stabilizing and chelating agent in injectable solutions, ophthalmic preparations, and topical formulations to sequester trace metal impurities.
• Analytical Chemistry Reagent: Serves as a key component in buffer solutions for complexometric titrations and as a masking agent in spectroscopic analysis (e.g., AAS, ICP).
• Industrial Cleaning & Detergents: Enhances the performance of industrial cleaners, scale removers, and detergent builders by effectively controlling water hardness ions.
• Pulp & Paper Processing: Acts as a chelant in bleaching processes and as a stabilizer for hydrogen peroxide, improving pulp brightness and process efficiency.
• Textile Treatment: Used in dyeing and finishing processes to prevent metal-ion catalyzed degradation of dyes and fabrics.
• Water Treatment: Employed in boiler and cooling water systems to inhibit scale formation and corrosion caused by calcium and magnesium salts.
• Laboratory Research: A critical reagent in biochemical and molecular biology research for preparing metal-free buffers and media.
• Agriculture: Incorporated into certain agrochemical formulations to improve stability and bioavailability.

Quality Control

Our Cdta Sodium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the high standards required for pharmaceutical and industrial applications. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting key parameters such as assay, purity, and heavy metal content. Specifications can be aligned with pharmacopeial standards (USP/EP) or customized to meet specific customer requirements.

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 container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or reduced performance.
