Description

Disodium 2,2'-(Methylimino)Bisethanesulphonate is a high-purity, water-soluble organic sulfonate salt with excellent chelating and buffering properties. This compound is valued for its ability to stabilize formulations and control metal ion activity in demanding industrial and laboratory processes. It is primarily sought by manufacturers and researchers in the pharmaceutical, biotechnology, and specialty chemical sectors for use as a critical buffer component and stabilizer.

Application

• Biochemical & Pharmaceutical Buffer: A key component in cell culture media, diagnostic reagent kits, and protein purification buffers to maintain precise pH stability.
• Stabilizing Agent: Used to enhance the shelf-life and stability of sensitive enzymes, antibodies, and other biological molecules in solution.
• Chelating Agent: Effective in sequestering trace metal ions (e.g., Ca²⁺, Mg²⁺) that can catalyze degradation reactions in pharmaceutical and cosmetic formulations.
• Electroplating Additive: Serves as a brightener and complexing agent in specialty electroplating baths to improve deposit quality and uniformity.
• Polymerization Aid: Acts as a surfactant or stabilizer in the production of certain specialty polymers and latexes.
• Laboratory Reagent: Employed in analytical chemistry and research as a standard or buffer for specific methodological applications.

Quality Control

Our Disodium 2,2'-(Methylimino)Bisethanesulphonate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identification (IR, NMR), and tests for impurities and residual solvents, to ensure it meets high-purity standards suitable for research and industrial applications. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled 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 affect product quality and handling.
