The IUPAC Gold Book is an exemplar of an important asset of IUPAC that is digitally represented for preservation, maintenance, dissemination, programmatic access, and semantic application.
The International ￼￼￼￼System of Units is getting a makeover. All of the new definitions are expressed in terms of seven ‘defining constants’ and the numerical values of these seven constants when expressed in SI units, provides the definition of all SI units.
To facilitate the continually-increasing global trade in chemicals and to manage it safely, understanding toxicology has become essential to the classification of toxicity, accurate labelling, and the production of accompanying safety data sheets. The glossaries are valuable toxicology references for students and researchers, as well as for those involved in chemicals legislation, regulation, management, and risk assessment.
Climate and air quality computer models are important tools which integrate our knowledge of emissions, observations, atmospheric chemistry, and meteorology. The IUPAC Task Group on Atmospheric Chemical Kinetic Data Evaluation provides the evaluated chemical data for atmospheric chemistry used in these models.
The written and spoken word are no longer sufficient in an era of digital information and interoperable data exchange world-wide. IUPAC is taking a leading role in the development of a new language for chemistry – one that is understandable by both humans AND their computers!
Since 2011, IUPAC has recognized the contributions that women have made in the field and presented a number of the women with the IUPAC Distinguished Women in Chemistry or Chemical Engineering Award. Who are they?
Atomic weights are of fundamental importance in science, technology, trade and commerce. It is therefore not surprising that the measurement of atomic weights has played a central role in the development of chemistry and continues to be a key component in the progress of discipline.
This story is about a book series which IUPAC supports via its project system. It is one of many examples of how successful and effective IUPAC is in supporting the development a diverse portfolio of essential tools for the global application and communication of chemical knowledge.
When a nomenclature question arises, the first reaction is often: what is the name that IUPAC gives? Accurate and widely accepted nomenclature is a vital need for communication amongst more than academic chemists and IUPAC chemical nomenclature is widely regarded as the world standard.
What are isotopes, and why do I need to know about them? These resources will explore these questions and more, including how the new atomic weight intervals came to be, and how to use them.
Find out why the work of IUPAC, providing a common language for scientists, is critical to society and could save your life.
Wikipedia is an important tool used by many chemists and chemistry students. But how do you verify that chemical information is correct?
“The InChIKey indexing has therefore turned Google into a de‑facto open global chemical information hub by merging links to most significant sources, including over 50 million PubChem and ChemSpider records.”
