Buy Benzimidazole (opioids) Cas 15451-92-0

Benzimidazole opioids are a class of synthetic opioids that contain a benzimidazole core structure. The pain-relieving properties of these substances were discovered in the mid-1950s by the Swiss company Ciba AG. The most important subgroup are the nitazene opioids, which since 2019 have become increasingly widespread as narcotics in North America and Europe, as well as West Africa. Some other benzimidazole-containing opioids are classified separately under the orphine subgroup. There is currently no medical usage due to the high potencies of certain analogs.^[1]

In 1957, the pharmaceutical research department of Ciba AG published the discovery of the (low) analgesic effect of 1-(β-diethylaminoethyl)-2-benzylbenzimidazole (desnitazene).^[2] Shortly afterwards, the nitazenes were discovered in structure-activity relationship studies.^[3][4]
