Source & Nature
Veronalum is the homeopathic name for barbital (barbitone), the first commercially marketed barbiturate sedative-hypnotic. It is the simplest barbiturate: 5,5-diethylbarbituric acid (diethylmalonylurea), molecular formula C8H12N2O3, CAS 57-44-3, PubChem CID 2294. It was first synthesized in 1902 by Emil Fischer and Joseph von Mering (published 1903) and introduced by Bayer in 1904 under the trade name "Veronal" (named after the Italian city of Verona); its soluble sodium salt was marketed by Schering as "Medinal." Chemically it is an odorless, slightly bitter, white crystalline powder. Pharmacologically it is a long-acting CNS depressant of the barbiturate class, used commercially as a hypnotic/sedative for insomnia from c.1904 until the mid-20th century, when it was superseded by safer agents.
