Description

Cyclohexanediamine Tetraacetic Acid CAS NO 25637-70-1 is a high-purity, versatile chelating agent and complexing compound. It is valued for its strong ability to sequester metal ions, forming stable complexes across a wide pH range. This makes it an essential component for industries requiring precise metal control, including pharmaceuticals, water treatment, and specialty chemical synthesis.

Application

• Pharmaceutical Synthesis: Acts as a key intermediate or complexing agent in the production of active pharmaceutical ingredients (APIs) and contrast agents.
• Industrial Water Treatment: Used as a scale and corrosion inhibitor in boiler and cooling water systems by chelating calcium, magnesium, and other metal ions.
• Chemical Manufacturing: Serves as a stabilizer, catalyst, or metal scavenger in various organic synthesis and polymerization processes.
• Analytical Chemistry: Employed as a masking agent in titrations and other analytical techniques to prevent interference from specific metal ions.
• Cleaning Formulations: Incorporated into industrial and institutional cleaners to enhance performance by controlling water hardness.
• Cosmetic & Personal Care: Functions as a chelator in formulations to improve stability and shelf-life by binding trace metals.
• Agrochemicals: Used in the synthesis of certain herbicides and pesticides where metal complexation is required.
• Pulp & Paper Industry: Applied in bleaching processes to deactivate metal ions that can catalyze the degradation of cellulose.

Quality Control

Our Cyclohexanediamine Tetraacetic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for industrial and technical applications. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and impurity profiles are available upon request to support your quality assurance protocols.

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); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product quality.
