Description

Choline Iodide is an organoiodine compound and a quaternary ammonium salt, serving as a vital source of both choline and bioavailable iodine. This dual functionality makes it a critical reagent and additive in advanced pharmaceutical synthesis and nutritional research. It is primarily utilized by manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, and fine chemical sectors for applications requiring precise iodine incorporation or cholinergic activity.

Application

• Pharmaceutical Intermediates: A key building block in the synthesis of iodine-containing active pharmaceutical ingredients (APIs) and radiocontrast agents.
• Nutraceutical & Dietary Supplements: Used as a source of bioavailable iodine and choline in specialized nutritional formulations and research compounds.
• Organic Synthesis: Acts as an alkylating agent and a source of iodide ions in various nucleophilic substitution and catalyst systems.
• Biochemical Research: Employed in cell culture media and as a reagent in studies related to choline metabolism, neurotransmission, and thyroid function.
• Liquid Crystal & Electronic Materials: Utilized in the production of certain ionic liquid crystals and as a precursor in material science applications.
• Animal Nutrition: Incorporated into specialized feed premixes for livestock to support metabolic health.
