Tetramethylammonium chloride is efficiently produced by the reaction of trimethylamine and methyl chloride. [3]N(CH 3) 3 + CH 3 Cl → N(CH 3) 4 + Cl −. It is produced by the alkylation of ammonium chloride with dimethyl carbonate in the presence of an ionic liquid catalyst.

Technetium forms a dioxide, [7] disulfide, diselenide, and ditelluride.An ill-defined Tc 2 S 7 forms upon treating pertechnetate with hydrogen sulfide.It thermally decomposes into disulfide and elemental sulfur. [8]
Technetium 99m Tc albumin aggregated (99m Tc-MAA) is an injectable radiopharmaceutical used in nuclear medicine.It consists of a sterile aqueous suspension of Technetium-99m (99m Tc) labeled to human albumin aggregate particles.
Technetium-99m (99m Tc) is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium), symbolized as 99m Tc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope in the world.
Five modern technetium-99m generators The first technetium-99m generator, unshielded, 1958. A Tc-99m pertechnetate solution is being eluted from Mo-99 molybdate bound to a chromatographic substrate
Technetium-99 (99 Tc) is an isotope of technetium which decays with a half-life of 211,000 years to stable ruthenium-99, emitting beta particles, but no gamma rays.It is the most significant long-lived fission product of uranium fission, producing the largest fraction of the total long-lived radiation emissions of nuclear waste.
