Molybdenum-99 (Mo-99)

Molybdenum-99 (Mo-99) Nitrate
Half-Life: 66.02 (hours)

Molybdenum-99 (Mo-99) is the parent of Technetium-99m (Tc-99m), the most widely applied isotope in nuclear medicine diagnostics today. Its short 6-hour half-life and the amount of emitted energy (140 keV) make Tc-99m a perfect imaging agent. Mo-99 is essential in Technetium generator manufacturing. 

Isotope JSC has been a reliable supplier of medical isotopes to nuclear medicine facilities for over 55 years. We represent ROSATOM State Corporation's companies which manufacture high-quality isotope products including Mo-99.

The manufacturers: 

  • RIAR, JSC;
  • Karpov IPC, JSC. 

Both manufacturers possess unique engineering expertise and production capacitites that comprise three reactors producing Mo-99 and two radiochemical laboratories. Well-coordinated production planning makes it possible for the two manufacturers to back up each other in case of an unplanned reactor outage. That is why, being the sole distributor of the Russian Mo-99, Isotope JSC can ensure reliable deliveries of this isotope to any customer. Our client-oriented approach has made us one of the leaders in the global isotope sales market.


Isotope JSC has a world-class distribution system using a unique order management software. Thanks to attentively managed logistics, we ensure on-time deliveries of all our products.
