17-methyl steroid

Dextromethorphan is the dextrorotatory enantiomer of levomethorphan , which is the methyl ether of levorphanol , both opioid analgesics . It is named according to IUPAC rules as (+)-3-methoxy-17-methyl-9α,13α,14α- morphinan . As its pure form, dextromethorphan occurs as an odorless, opalescent white powder. It is freely soluble in chloroform and insoluble in water ; the hydrobromide salt is water-soluble up to /100 mL at 25 °C. [31] Dextromethorphan is commonly available as the monohydrated hydrobromide salt, however some newer extended-release formulations contain dextromethorphan bound to an ion-exchange resin based on polystyrene sulfonic acid . Dextromethorphan's specific rotation in water is +° (20 °C, Sodium D-line). [ citation needed ]
