Application

Pentobarbital sodium salt has been used as an anesthetic in rats and mice prior to various in vitro studies.

Biochem/physiol Actions

Pentobarbital (PB) is a barbiturate and a ligand of the γ-aminobutyric acid subtype A (GABAA) receptor. It is a sedative anesthetic majorly used in rodent euthanasia. Pentobarbital possesses hypnotic functionality and muscle relaxing properties. It enhances GABAergic activity. Intraperitoneal injection of PB may result in loss of righting reflex (LORR) and heartbeat cessation.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How can I solubilize Pentobarbital sodium salt, Product P3761?

    This product is soluble in water (50 mg/ml), with heat and sonication as needed, yielding a clear to slightly hazy, colorless solution.

  4. How can I store my solution of Pentobarbital sodium salt, Product P3761?

    Solutions of the sodium salt are typically pH 9.0 - 11.0 (BP/USP). If the pH is lowered, the free acid will precipitate from solution. Solutions decompose on standing, the decomposition being accelerated at higher temperatures.  We recommend to make solutions fresh.
