Description

Sulfoacetic Acid Monohydrate is a versatile organosulfur compound that combines the properties of a carboxylic acid and a sulfonic acid. This unique bifunctional structure makes it a valuable intermediate and reagent in advanced chemical synthesis and industrial processes. It is essential for manufacturers and R&D facilities in the pharmaceutical, agrochemical, and specialty chemical sectors seeking to introduce sulfonate or carboxylate functionalities.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring sulfonate groups for enhanced solubility or biological activity.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where its acidic groups facilitate the creation of effective salts and esters.
• Chemical Research & Development: Serves as a precursor and catalyst in various organic reactions, including esterification and sulfonation processes.
• Surfactant and Detergent Industry: Acts as an intermediate for producing anionic surfactants with high stability and cleaning efficiency.
• Polymer Modification: Employed to introduce ionic character or cross-linking sites into polymers, improving their properties for specific technical applications.
• Electroplating Additives: Utilized in specialized electroplating baths to improve finish quality and deposition efficiency.

Quality Control

Our Sulfoacetic Acid Monohydrate is produced under a stringent quality management system. Each batch is tested to ensure it meets precise chemical and physical specifications, with a focus on purity, consistency, and absence of critical impurities. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from strong bases and incompatible materials.
