What on Earth is InChI?
Watch this set of videos to find out more about the InChI and why it’s so cool.
The first video introduces the InChI standard to represent chemical structures. The second describes the background to the development of the InChI standard. The third is about the Googleable InChI Key. And the fourth explains how InChI enables the linking of information.


The Hague Ethical Guidelines

The IUPAC Bureau has approved a request from OPCW to endorse and promote the Guidelines
The Hague Ethical Guidelines are intended to serve as elements for ethical codes and discussion points for ethical issues related to the practice of chemistry.
