Educational resources
Chem Edu Int
  The online newsletter of the Committee on Chemistry Education presents reports, facts and figures, as well as opinions and essays.
Chemical Safety - Essential Toxicology
  This collection of presentations provides educators with materials for teaching and learning the fundamentals of toxicology. Educators should select those materials appropriate for their own local requirements and supplement them with examples relevant to their students.
  This extensive series of educational illustrations gives science and chemistry teachers a practical working tool to present diagrams and situations which are complicated to draw. Other more entertaining drawings can also be used to present a particular fact or concept, in the hope that visual imagery will permit the concepts to be more easily understood.
Micro-Scale Chemistry
  Practical work is an integral part of science education. A joint UNESCO/IUPAC project aims to introduce teachers to the advantage of performing chemistry experiments on a small scale. Teachers' Guide & Students Worksheets are made available via the UNESCO Global Microscience Project.
Periodic Table of the Elements
  Link to the IUPAC table in a printable (letter size) format, and snap-shot of the time of discovery.
Polymer Education

This resource website maintained by the IUPAC Polymer Division constitutes an easy starting point for searching educational resources related to polymers. Check the CD and do not miss checking the mini movies and many more.

Practical Studies for Medicinal Chemistry
  This collection of 41 laboratory exercises is representative of the field of Medicinal Chemistry. The exercises are easy to reproduce and in many cases interdisciplinary. Some of them consider natural products as the work material.


  The aim of this site is to ensure the dissemination of accurate information on the chemistry of agrochemicals and the regulations pertaining to their use in one web site and in an easy to use format. The site also gives access to the FOOTPRINT PPDB (Pesticide Properties Database).
Aqueous Solutions
  A package of programs for the quantitative treatment of activity coefficients and a wide range of equilibria in solutions of varying backgrounds, ionic strengths and temperatures. Includes software for speciation calculations and titration simulations.
C-NPU - Nomenclature, Properties, and Units in Laboratory Medicine
  This database contains the current C-NPU coded properties; it is searchable by C-NPU code (e.g. NPU01234) or by the elements of which the properties consist (e.g. blood).
Gas Kinetic Database
  This website provides kinetic and photochemical evaluated data in the form of summary tables of kinetic data and individual sheets of reaction data, e.g. for some heterogeneous reactions, a number of halogen, Ox, HOx, NOx and SOx photolysis reactions, and a number of gas-phase Ox, HOx, NOx, SOx and organic reactions.
k0-NAA database
  This database contains data essential for calculation of analytical results from neutron-activation analysis (NAA). The method used is a comparator method called the k0 method. The database includes recommended values for k0 and other relevant nuclear data.
Solubility Database
  The database covers solubilities originally published in the IUPAC-NIST Solubility Data Series. Mutual solubilities and liquid-liquid equilibria of binary, ternary and quaternary systems are presented. Typical solvents and solutes include water, sea water, heavy water, inorganic compounds, and a variety of organic compounds such as hydrocarbons, halogenated hydrocarbons, alcohols, acids, esters and nitrogen compounds.
Stability Constants Database
  This database gives very fast access to all significant published metal-ligand stability constants with over 22000 literature references and with interactive applications to display speciation curves, to correct for temperature or ionic strength changes etc.

Nomenclature and Terminology (including IUPAC color books)
> link to all IUPAC color books references <www.iupac.org/publications/books/seriestitles/nomenclature.html>

Chemical Terminology (Gold book)
  > Advanced XML version <http://goldbook.iupac.org>
The IUPAC Compendium of Chemical Terminology is the definitive guide to chemical terminology; it now contains more than 7000 entries, is easy to browse, search, and navigate.
Quantities, Units and Symbols in Physical Chemistry (Green book)
  This book provides a readable compilation of widely used terms and symbols from many sources together with brief understandable definitions. Full text pdf with with bookmark by chapters and sections is available.
Nomenclature of Organic Chemistry (Blue book)
  HTML reproduction of the IUPAC Nomenclature of Organic Chemistry has been prepared by Advanced Chemistry Development, Inc and is searchable on the ACD website.
Macromolecular Nomenclature (Purple book)
  A second edition of the IUPAC Compendium of Macromolecular Nomenclature is currently in preparation; see draft content at www.iupac.org/projects/2002/2002-048-1-400.html
The existing Compendium (1991) consists of an introduction to macromolecular nomenclature and nine chapters corresponding to the then valid IUPAC recommendations.
Analytical Terminology (Orange book)
  The Web edition of the IUPAC Compendium on Analytical Terminology provides ease of access to the extensive information contained in its recommendations.
Biochemical Nomenclature
  The Biochemical Nomenclature and Related Documents (1992) presents IUPAC-IUBMB (International Union of Biochemistry and Molecular Biology) Joint Commissions' recommendations; it includes sections on amino acids, peptides and proteins, enzymes, nucleotides, nucleic acids and protein synthesis, carbohydrates, lipids, etc.


  The IUPAC International Chemical Identifier (InChI) is a non-proprietary identifier for chemical substances that can be used in printed and electronic data sources thus enabling easier linking of diverse data compilations. The source code and associated software and documentation are available on this web site.
  ThermoML is the reserved namespace for the XML-based IUPAC standard for experimental and critically-evaluated thermodynamic property data storage. It covers essentially all experimentally determined thermodynamic and transport property data (more than 120 properties) for pure compounds, multicomponent mixtures, and chemical reactions (including change-of-state and equilibrium).
