Profile
Scandium is a light metal used in multiple industries, including aluminium alloys for aerospace, industrial tracing, and lighting. Scandium-47 is a synthetic radioisotope produced for treatment, with a half-life of about 3.3 days.
Scandium-47 emits beta particles that deliver therapeutic radiation over a short range, together with a gamma photon suitable for SPECT imaging, so treatment and monitoring can use the same dose.
It is the therapeutic partner of the PET isotope scandium-44, forming a true element-matched theranostic set with identical chemistry enabling a treatment to be imaged, planned, delivered, and monitored without any change in how the agent behaves.
Scandium-47 can be produced by neutron irradiation of enriched calcium or titanium targets, or by accelerator routes using enriched titanium. Both demand costly enriched target material and careful separation to avoid long-lived scandium impurities, which has kept availability low.
StandardX is developing accelerator-driven production to supply clinical-scale, high-purity scandium-47 for element-matched theranostics.
