Tetrodotoxin citrate is the water-soluble citrate salt form of tetrodotoxin, retaining its potent and selective inhibition of voltage-gated sodium channels. Its enhanced solubility facilitates its use in in vitro and in vivo neuroscience studies. Tetrodotoxin citrate is employed to investigate neuronal signaling, action potential propagation, and sodium channel dysfunction in neurodegenerative and neuropsychiatric disorders.

Need this compound in a format that drops straight into your assay? We can tailor formulation, chemistry, and documentation so your results stay consistent across runs and re-orders.

  • Format options: solid or pre-dissolved solution (choose solvent), target concentration, aliquots, light/moisture-protected packaging
  • Chemistry options: free base/acid vs salt forms, hydrate/solvate preference, stereoisomer control (single enantiomer or racemate), close analogs
  • Add-on labels & handles: D/¹³C/¹⁵N isotopes (LC-MS/internal standards), azide/alkyne or other functional handles for conjugation
  • QC & documentation: standard COA or enhanced analytical pack (HPLC/LC-MS/NMR), chiral purity, residual solvents, water content (KF), method-specific specs
  • Scale & continuity: mg to gram scale, bulk pricing, lot reservation, repeat-order continuity

To quote quickly, tell us: compound name + CAS/structure (SMILES or mol file), intended assay context, solvent preference, salt/stereochemistry requirements, purity/QC level, and the amount (mg–g).
