Properties: Prismatic crystals, practically tasteless, mp 145-147°. Practically insol in water. One gram dissolves in about 3 liters of water. Sol in methanol, hot ethanol, ether, chloroform, acetone, benzene, aq solns of alkali hydroxides, but not carbonates.
Melting point: mp 145-147°
Derivative Type: Sodium salt
CAS Registry Number: 50-09-9
Additional Names: Hexobarbital soluble
Trademarks: Cyclonal Sodium; Dorico Soluble; Evipal Sodium (Winthrop); Evipan Sodium (Bayer); Hexanastab; Hexenal; Methexenyl Sodium; Noctivane Sodium; Narcosan Soluble; Privenal

Properties: White, bitter, very hygroscopic powder. Very sol in water, freely sol in alcohol, methanol, acetone. Practically insol in chloroform, ether, benzene. A soln in water absorbs carbon dioxide from the air, causing precipitation of the insol free acid. Aq and alcoholic solns are alkaline to litmus and phenolphthalein. The pH of a 10% w/v soln of hexobarbital soluble is about 11.5.
