English description(英文原文,共 932 字符)
Product Name:Potassium iodide
English Name:Potassium iodide
CAS No.:7681-11-0
Aliases:Thyroblock, Potassium monoiodide
Molecular Formula:KI
Physical Properties:White cubic crystals or powder, odorless, with a salty and slightly bitter taste. Relative density 3.13, melting point 681°C, boiling point 1323°C (partial decomposition). Freely soluble in water, soluble in ethanol, acetone and glycerol. The aqueous solution is neutral or slightly alkaline. Hygroscopic; turns yellow upon exposure to light and air due to liberation of free iodine.
Uses:Used as a pharmaceutical intermediate for synthesizing iodides and iodine-containing drugs; also applied in preparation of photographic emulsions, feed additives, iodized salt additives and analytical reagents.
Technical Specifications:
Assay (as KI) ≥99.0%
Water (H₂O) ≤0.5%
Heavy metals (as Pb) ≤0.001%
Chlorides (as Cl) ≤0.02%
Aqueous solution is clear and transparent
