Click here for FREE IUPAC Naming from ACD/I-Lab
Warning: this interactive naming service uses a Java applet the launching of which may take some seconds to some minutes depending on your network connection. Moreover, it has certain limitations (less than 50 atoms, no more than 3 cycles, no elements other than C, H, N, P, O, S, F, Cl, Br, I, Li, Na, K). If you want more, you may use the offline version (ChemSketch with I-Lab Add-in, both freely downloadable) or the commercial service.
