IUPAC Standards Online is a database containing IUPAC standards and recommendations, taken from the journal Pure and Applied Chemistry (PAC). These standards include standard values and procedures, rules for the designation of substances and materials, names and properties of elements in the periodic table, and much more. Thematically structured and with cross-linked entries, the database’s advanced search function allows for the quick and easy retrieval of IUPAC standards and recommendations which until now have remained unclassified within the extensive Pure and Applied Chemistry archive.

In addition to the IUPAC Standards Database, De Gruyter Brill is proud to partner with IUPAC in the publication of the society’s flagship monthly journal, Pure and Applied Chemistry, as well as the society’s quarterly newsmagazine, Chemistry International, and the new open access journal Chemistry Teacher International.
