Tetrodotoxin is a naturally occurring marine biotoxin found in pufferfish and certain other aquatic species, acting as a selective blocker of voltage-gated sodium channels and associated with severe neurotoxic poisoning. It is monitored in seafood safety programmes and in clinical and forensic investigations, so a well-characterised reference standard is needed for reliable identification and measurement. Typical laboratory use includes LC-MS/MS method development and validation, construction of calibration curves at low concentrations, recovery and matrix-effect evaluation in fish tissue, and confirmation of suspect samples against an authenticated material. The compound corresponds to the formula C11H17N3O8 with a molecular weight of 319.27 and is a white powder. It should be stored at -20 °C ± 5 °C and shipped with ice packs, and is available in 1 mg and 10 mg pack sizes. Enquiries for supporting documentation or a quotation are welcome.
