Sodium astatide is a binary inorganic compound of sodium and astatine with the chemical formula NaAt.[1][2]

Synthesis

Sodium astatide solution has been prepared by distilling astatine from the bismuth alpha-ray target where it was prepared, dissolving in sodium bicarbonate solution, and reducing At+ and At3+ ions with ascorbic acid.[3]

Uses

Sodium astatide has been proposed for use in radiation therapy to replace 131I.[4][3]
