Description

Potassium Triiodide (Aqueous Solution -- 75% To 80%) is a concentrated aqueous solution of the potassium salt of triiodide, a powerful oxidizing agent and a key source of iodine. This high-concentration solution is valued for its stability and reactivity, making it a critical reagent in analytical and synthetic chemistry. It is primarily sought by manufacturers and laboratories in the pharmaceutical, chemical research, and analytical sectors for its precise and potent iodinating and oxidizing capabilities.

Application

• Analytical Chemistry (Iodometry): A primary standard titrant for the quantitative determination of reducing agents like ascorbic acid (Vitamin C), sulfites, and thiosulfates.
• Pharmaceutical Synthesis: Used as an efficient iodinating agent in the production of active pharmaceutical ingredients (APIs) and fine chemicals.
• Starch-Iodine Test: Serves as the definitive reagent for the qualitative detection and quantitative analysis of starch in food, textile, and paper industries.
• Disinfectant & Biocide Formulation: Acts as a potent source of iodine for formulating specialized disinfectants and antimicrobial solutions.
• Chemical Research & Development: Employed in organic synthesis for oxidative coupling reactions and as a catalyst or reactant in various oxidation processes.
• Educational & Laboratory Use: A standard laboratory reagent for teaching and demonstrating redox reactions and analytical techniques.
