About IUPAC’s Scientific Work

Chemistry connects us all—from the water we drink to the medicines we take—and behind that connection is a shared scientific language. This document offers a quick look at how IUPAC helps build and sustain that language for over a century. If you’ve ever wondered who standardizes chemical terminology, or sets the guidelines for measuring and reporting data in labs around the world, you’re in the right place. Through international collaboration, scientific rigor and consensus, and community engagement, IUPAC brings order and clarity to the most complex fields of chemistry.
