DOTA-NHS-ester is an N-hydroxysuccinimide ester derivative of the DOTA chelator used to conjugate amine-containing molecules for radiolabeling and imaging probe development. It is supplied as a solid and is handled and stored under low-temperature, moisture-free conditions.

  • Used to conjugate DOTA to primary amines for PET and SPECT probe development.
  • High purity suitable for research applications.
  • Soluble in DMSO at 50 mg/mL; protocols provided for aqueous in vivo formulations.
  • Stable as a solid when stored sealed at -20 °C; dissolved samples have recommended cold storage times.
  • Molecular weight 501.49 and CAS number 170908-81-3 for unambiguous identification.
