The International Union of Pure and Applied Chemistry (IUPAC) is one of the most authoritative international organizations in the field of chemistry. Since its founding in 1919, IUPAC has been dedicated to promoting the development of chemical science globally, making outstanding contributions to the standardization, normalization, and internationalization of the field. Headquartered in Zurich, Switzerland, as a key member of the International Science Council (ISC), IUPAC plays an irreplaceable role in chemical research, education, industrial applications, and international exchange.
Background and history of IUPAC
The founding of IUPAC can be traced back to the early 20th century, a time of rapid global advancements in chemical science. However, differences in chemical nomenclature, terminology, and measurement standards among countries created numerous obstacles to international exchange and cooperation. To unify nomenclature rules and standardize the chemical field, chemists from various countries established the International Union of Pure and Applied Chemistry (IUPAC) in Paris in 1919. From its inception, IUPAC's primary goal was to develop an internationally accepted chemical nomenclature system to promote global exchange and cooperation within the chemical community.
Over time, IUPAC's responsibilities have expanded from its initial naming rules to all aspects of chemistry, including chemical education, research collaboration, and the development of technical standards. Today, IUPAC has become a leading authority in the global chemistry community, and its standards and specifications are widely used in academic research, industrial production, and education.

IUPAC's core mission is to advance chemical science globally, and its functions encompass multiple aspects of the field. The following are IUPAC's main functions:
1. Standardization of chemical nomenclature and terminology
IUPAC is best known for its role in developing chemical nomenclature and terminology standards. Chemical nomenclature is a complex and precise discipline, and naming rules often differ between regions and countries. To eliminate these differences, IUPAC has developed an internationally accepted chemical nomenclature system covering multiple fields, including organic chemistry, inorganic chemistry, and polymer chemistry. This system not only simplifies chemical communication but also provides a unified reference standard for chemical education.
2. Publication and promotion of chemical literature
IUPAC regularly publishes chemistry-related academic journals, technical reports, and standardization documents, providing the global chemistry community with the latest research findings and technical information. Among them, IUPAC's official journal, *Pure and Applied Chemistry*, is a leading academic publication in the field of chemistry, publishing a large number of high-quality research papers and review articles. In addition, IUPAC also promotes chemistry knowledge to the public and enhances the social impact of chemical science through its official website and publications.
3. Chemistry Education and Talent Cultivation
IUPAC places great importance on chemistry education and is committed to cultivating the next generation of chemistry scientists. To this end, IUPAC collaborates with numerous universities and research institutions worldwide to conduct chemistry education programs, providing teaching resources and training courses. In addition, IUPAC has established several scholarship and award programs to encourage young scientists to achieve excellence in the field of chemistry.
4. International Scientific Research Cooperation and Exchange
IUPAC promotes exchange and cooperation within the global chemistry community by organizing international conferences, workshops, and collaborative projects. These activities provide a platform for chemical scientists to share research findings and discuss cutting-edge issues, driving innovative development in chemical science. Furthermore, IUPAC collaborates with other international scientific organizations to address global challenges such as climate change, the energy crisis, and environmental pollution.
5. Formulation of Chemical Technology Standards
IUPAC plays a vital role in the development of chemical technical standards. Its standards cover multiple fields, including chemical analysis, experimental methods, and measurement techniques, providing reliable references for chemical research and industrial production. These standards not only improve the accuracy and repeatability of chemical experiments but also promote the internationalization and standardization of chemical technologies.
IUPAC's organizational structure and operating model
IUPAC's organizational structure comprises multiple committees and working groups, each responsible for different functions and areas. The following is IUPAC's main organizational structure:
1. Executive Committee
The Executive Committee is the highest decision-making body of IUPAC, responsible for formulating the organization's strategic direction and major decisions. The Executive Committee consists of a Chairperson, Vice-Chairpersons, Secretary-General, and Treasurer, whose members are elected by all IUPAC members.
2. Specialized Committees
IUPAC has several specialized committees responsible for work related to chemical nomenclature, chemical education, and chemical technical standards. These committees, composed of chemical experts from around the world, meet regularly to discuss and develop relevant standards and policies.
3. National Representative Committee
IUPAC's members include chemical societies and research institutions from various countries. Each member country has a national representative responsible for communication and coordination with IUPAC. The National Representative Committee meets regularly to discuss the development of chemistry in each country and their cooperation needs.
4. Working Group and Project Team
To address specific problems in the field of chemistry, IUPAC has established several working groups and project teams. These groups, composed of chemistry experts, focus on research and standardization work in a particular area. For example, IUPAC's Polymer Chemistry Working Group is responsible for developing nomenclature and classification standards for polymer materials.
IUPAC's major achievements and contributions
Since its inception, IUPAC has achieved numerous significant accomplishments in the field of chemistry. Its contributions have not only propelled the development of chemical science but have also had a profound impact on industries, medicine, and environmental protection. The following are some of IUPAC's major achievements and contributions:
