Benzylmorphine (Peronine) is a semi-synthetic opioid narcotic introduced to the international market in 1896 and that of the United States very shortly thereafter. It is much like codeine, containing a benzyl group attached to the morphine molecule just as the methyl group creates codeine and the ethyl group creates ethylmorphine or dionine (used as a generic name for that drug just as peronine is for benzylmorphine). It is about 90% as strong as codeine by weight.

This drug, the benzyl ether of morphine, should not be confused with dibenzoylmorphine, an ester of morphine comparable to heroin. Another morphine ether developed around the same time, benzyldihydromorphine, saw some clinical use in the opening years of the 20th century. The ethers of morphine and codeine as well as dihydromorphine and dihydrocodeine number close to 100 and include such obscure opioids as formylallopseudoisocodeine.
