Description

Edta, Disodium Cobaltous Salt CAS NO 24704-41-4 is a coordination compound formed from ethylenediaminetetraacetic acid (EDTA) and cobalt(II) ions, stabilized as a disodium salt. This specialized chelating agent is valued for its ability to form a highly stable, water-soluble complex with cobalt, controlling its reactivity and bioavailability. It is essential for manufacturers and researchers in the pharmaceutical, analytical chemistry, and industrial catalyst sectors requiring precise metal ion management.

Application

• Pharmaceutical Synthesis & Formulations: Acts as a cobalt source or stabilizer in the production of vitamin B12 (cyanocobalamin) and other cobalt-containing active pharmaceutical ingredients (APIs).
• Analytical Chemistry Reagent: Used as a standard, titrant, or masking agent in complexometric titrations and spectroscopic analysis for the determination of various metal ions.
• Catalyst & Chemical Intermediate: Serves as a precursor or component in homogeneous catalysis for oxidation reactions and organic synthesis processes.
• Nutritional & Feed Additives: Employed as a source of bioavailable cobalt in trace mineral premises for animal feed.
• Laboratory Research: Utilized in biochemical and environmental studies to buffer or control free cobalt ion concentration in experimental systems.
• Industrial Process Stabilizer: Functions as a metal deactivator and stabilizer in certain polymer and chemical manufacturing processes to prevent unwanted catalytic degradation.
