International Union of Pure and Applied Chemistry
The International Union of Pure and Applied Chemistry is the global organization that provides objective scientific expertise and develops the essential tools for the application and communication of chemical knowledge for the benefit of humankind and the world. IUPAC accomplishes its mission by fostering sustainable development, providing a common language for chemistry, and advocating the free exchange of scientific information. In fulfilling this mission, IUPAC effectively contributes to the worldwide understanding and application of the chemical sciences, to the betterment of humankind.www.iupac.org

Deboki ChakravartiHOST
To get common names, the alkyl group attached to the amine group is put before amine in the name, like methylamine, ethylamine, or propylamine.
Deboki ChakravartiHOST
And, of course, there's IUPAC, which we'll put on the screen.
Deboki ChakravartiHOST
These are all examples of primary amines, amines where one alkyl or aryl group is attached to the nitrogen in the amine group.
Deboki ChakravartiHOST
Just like we have primary, secondary, and tertiary alcohols, we can have secondary and tertiary amines too.
Deboki ChakravartiHOST
So, a secondary amine with a methyl and an ethyl group attached to the nitrogen would be ethyl methyl amine.
Deboki ChakravartiHOST
And the fishy-smelling trimethylamine is a tertiary amine, with three methyl groups attached to the nitrogen.
Deboki ChakravartiHOST
The NH2 group is pretty low priority in IUPAC nomenclature, so we'll often see its prefix name, amino, when there are higher-priority functional groups in a molecule, like 5-amino-2-pentanone and 4-aminobenzoic acid.
Deboki ChakravartiHOST
Some molecules have more than one amine group.
Mathieu DenisPANELIST
It's not gonna be the same things, but we need to find the forms, and again, the notion of leadership and ACS and some of the other big discipline scholarly bodies that are here can, can help us think through what that might look like.
Mathieu DenisPANELIST
I think that working on, for example, joint and shared standards, nomenclatures, identifiers, the kind of work that ACS does, but also our colleagues from the International Union of Pure and Applied Chemistry, is critically important.
Mathieu DenisPANELIST
It's the basis.
Mathieu DenisPANELIST
It helps us maintain the relationship.
speaker_0HOST
That is wild.
speaker_1HOST
The controversy was so intense that the International Union of Pure and Applied Chemistry, IUPAC, which is the governing body of chemical nomenclature, they actually had to step in.
speaker_0HOST
They had to mediate.
speaker_1HOST
They convened a special working group, essentially a scientific tribunal, to pore over the highly classified secret lab notebooks from both Berkeley and Dubna to determine who actually had the data to prove discovery.
