| Hazard Information | Back Directory | [Chemical Properties]
White crystals. | [Definition]
ChEBI: A member of the class of barbiturates taht is barbituric acid substituted at N-1 by methyl and at C-5 by methyl and cyclohex-1-enyl groups. | [Description]
Hexobarbital, 5-(cyclohexen-1-
yl)-1,5-dimethylbarbituric acid,Mr 236.26. The
acid forms colorless crystals that turn pink on exposure
to light, mp 146 ?C. A 10 % aqueous solution
of the sodium salt, Mr 258.25,
has a pH of 11.5. | [Brand name]

Hexobarbital is a short-acting barbiturate. See WHO comment for
barbiturates. | [Clinical Use]
Methohexital sodium is a short-acting anesthetic
administered intravenously. It is very potent
and has the shortest duration of action
among the barbiturates used. A disturbing factor
is that rather frequently it causes hiccups directly
after injection. Patients are reported to recover
rapidly from anesthesia. Abuse can lead to addiction. | [Synthesis]
Hexobarbital sodium is prepared by condensation
of methyl(cyclohexen-1-yl)cyanoacetic
ester with dicyanodiamide to 5-(cyclohexen-
1-yl)-5-methyl-2,6-diimino-3-cyanobarbituric
acid, followed by methylation with dimethyl
sulfate and hydrolysis with 25 % sulfuric acid
