Understanding IOSAT and Its API

What is IOSAT?
IOSAT typically contains potassium iodide (KI) as its active ingredient. It acts as a protective agent against radioactive iodine uptake in the thyroid gland, reducing radiation risk following nuclear incidents or during certain medical procedures.

API of Interest: Potassium Iodide (KI)
The API for IOSAT is potassium iodide, a well-established compound with extensive use in radioprotection. Despite its long history, sourcing high-quality KI requires adherence to stringent standards because of its medical application.
