• Recent ClinicalTrials: Preoperative Preparation With Lugol Solution in Patients With Graves-Basedow Disease.
• Uses: Lugol solution has been used in a study to assess narrow-band imaging without image magnification for detecting high-grade dysplasia and intramucosal esophageal squamous cell carcinoma. It has also been used in a study to determine its benefit in aiding detection of the presence and spread of small squamous cell carcinomas of the esophagus.

Technology Process of Potassium triiodide

There total 5 articles about Potassium triiodide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

iodine (7553-56-2,12190-71-5,8031-47-8) + potassium bromide (7558-02-3,7758-02-3) → potassium triiodide (12298-68-9,153507-24-5) + iodine(I) bromide (7789-33-5)

Guidance literature:
