Dertail:
Barbital (or barbitone), marketed under the brand names Veronal for the pure acid and Medinal for the sodium salt, was the first commercially available barbiturate. It was used as a sleeping aid (hypnotic) from 1903 until the mid-1950s. The chemical names for barbital are diethylmalonyl urea or diethylbarbituric acid; hence, the sodium salt (known as medinal, a genericised trademark in the United Kingdom) is known also as sodium diethylbarbiturate.
Synthesis:
Barbital was first synthesized in 1902 by German chemists Emil Fischer and Joseph von Mering, who published their discovery in 1903. Barbital was prepared by condensing diethylmalonic ester with urea in the presence of sodium ethoxide, and then by adding at least two molar equivalents of ethyl iodide to the silver salt of malonylurea or possibly to a basic solution of the acid. The result was an odorless, slightly bitter, white crystalline powder.
Pharmacology:
Barbital was considered to be a great improvement over the existing hypnotics. Its taste was slightly bitter, but better than the strong, unpleasant taste of the commonly used bromides. It had few side effects, and its therapeutic dose was far below the toxic dose. However, prolonged usage resulted in tolerance to the drug, requiring higher doses to reach the desired effect. "I'm literally saturated with it," the Russian tsarina Alexandra Feodeorovna confessed to a friend. Fatal overdoses of this slow-acting hypnotic were not uncommon. Pioneering aviator Arthur Whitten Brown (of "Alcock and Brown" fame) died of an accidental overdose.Japanese writer Ryūnosuke Akutagawa deliberately overdosed on the drug in 1927.
pH buffer:
Solutions of sodium barbital have also been used as pH buffers for biological research, e.g., in immunoelectrophoresis or in fixative solutions. As barbital is a controlled substance, barbital-based buffers have largely been replaced by other substances.
