Examples and uses

Benomyl is a fungicide with a benzimidazole core

The chemical compound can be found in

  • Angiotensin II receptor blockers such as azilsartan, candesartan, and telmisartan.
  • Anthelmintic agents such as albendazole, ciclobendazole, fenbendazole, flubendazole, mebendazole, oxfendazole, oxibendazole, triclabendazole, and thiabendazole.
  • Antihistamines such as astemizole, bilastine, clemizole, emedastine, mizolastine, and oxatomide.
  • Benzimidazole fungicides such as benomyl, carbendazim, fuberidazole, and thiabendazole.
  • Benzimidazole opioids such as bezitramide, brorphine, clonitazene, etodesnitazene, etonitazene, etonitazepipne, etonitazepyne, isotonitazene, metodesnitazene, and metonitazene.
  • Proton-pump inhibitors such as dexlansoprazole, esomeprazole, ilaprazole, lansoprazole, omeprazole, pantoprazole, rabeprazole, and tenatoprazole.
  • Typical antipsychotics such as benperidol, clopimozide, droperidol, neflumozide, and oxiperomide, and pimozide.
  • Benzimidazole can also be found in abemaciclib, bendamustine, dabigatran, daridorexant, and glasdegib.

When printed circuit boards are manufactured (or made), benzimidazole can be used as an organic solderability preservative. (When that kind of preservative gets used, it can protect copper contacts (for years), until the contact gets soldered.)
