HCN എന്ന് രാസനാമമുള്ള ഒരു ജൈവ സംയുക്തമാണ്^[8] ഹൈഡ്രജൻ സയനൈഡ് (Hydrogen cyanide). നിറമില്ലാത്ത ഈ സംയുക്തം അന്തരീക്ഷ താപനിലയേക്കാൾ അൽപ്പം ഉയർന്ന താപത്തിൽ വാതകമായി മാറുന്നു. തിളനില 25.6 °C (78.1 °F) ആയ ഹൈഡ്രജൻ സയനൈഡ് മാരകമായ വിഷമുള്ള ഒരു പദാർത്ഥമാണ്. വലിയ വിലപിടിച്ച വ്യാവസായിക ഉൽപ്പന്നമായ ഹൈഡ്രജൻ സയനൈഡ് പോളിമറുകളുടെ മുതൽ ഔഷധങ്ങളുടെ വരെ നിർമ്മാണത്തിന് ഉപയോഗിക്കുന്നു.
