Potassium pertechnetate is a chemical compound of technetium and potassium, with the chemical formula of KTcO4.
Potassium pertechnetate can be obtained by the neutralisation of potassium hydroxide and pertechnetic acid:[2]
The distance of the Tc–O bond in potassium pertechnetate is 173.9 pm and the angle of the O–Tc–O bond is 108.05° and 110.19°. The distance between the potassium and the oxygen is 289.36 pm and 286 pm.[2] Potassium pertechnetate crystallizes in the tetragonal crystal system with space group I41/a (space group no. 88). The lattice parameters are a = 563.0 pm and c = 1286.7 pm.[3]
Potassium pertechnetate is used to prepare other radiopharmaceuticals.[2]
