Description

Iminodisuccinic Acid CAS NO 131669-35-7 is a biodegradable, high-performance chelating agent and scale inhibitor. This compound is valued for its strong binding affinity for polyvalent metal ions, such as calcium, magnesium, and iron, under a wide range of pH conditions. It is essential for industries requiring effective water treatment, metal cleaning, and environmentally friendly formulations to replace traditional phosphonates and EDTA.

Application

• Industrial Water Treatment: As a key component in cooling water and boiler water systems to prevent scale formation and inhibit corrosion.
• Pulp & Paper Industry: Used in bleaching processes to chelate metal ions that can catalyze the decomposition of bleaching agents and degrade pulp quality.
• Detergents and Cleaners: Serves as a biodegradable builder and chelant in laundry detergents, dishwashing liquids, and industrial cleaners to enhance cleaning efficiency and soften water.
• Agriculture: Employed in micronutrient fertilizers and agrochemical formulations to improve the bioavailability of essential metal ions for plants.
• Textile Processing: Acts as a chelating agent in dyeing and printing processes to prevent metal-ion interference and ensure color fastness.
• Oilfield Chemicals: Used in scale inhibitor formulations for oil and gas production to manage mineral scale in wells and pipelines.
• Personal Care: Incorporated into cosmetic and personal care products as a stabilizer and chelant to protect formulation integrity.

Quality Control

Our Iminodisuccinic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets high-purity standards and consistent performance. Certificates of Analysis (COA) documenting key parameters such as assay, chelation value, 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); ensure the original container is kept sealed to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
