國際純化學和應用化學聯合會（International Union of Pure and Applied Chemistry，IUPAC）簡稱國際化聯，又譯國際純粹與應用化學聯合會、國際純化學與應用化學聯盟、國際純化學與應用化學協會、國際理論與應用化學聯合會或國際理論與應用化學聯盟，是一個聯合國家會員組織，代表各國化學家的國際聯盟，屬國際科學理事會（ISC）的成員之一[1]。IUPAC的國際總部設於瑞士蘇黎世；其行政辦公室，或稱IUPAC秘書處，位於美國北卡羅萊納州的三角研究園。這所行政辦公室由IUPAC的理事長帶領[2]。截至2012年8月1日的理事長為John D.

Michael D. Gordin. Scientific Babel How Science Was Done Before and After Global English. University of Chicago Press. 13 April 2015: 178–180. ISBN 978-0-226-00029-9（英語）. If the Boycott of German scholars from conferences was the short-term punishment for perceived misdeeds during the war, the IRC's second action would have more lasting consequences for the fate of German as a scientific language. ... To this day, IUPAC governs global chemistry, serving the court of final recourse to adjudicate discovery claims of new elements (and the right to name them, thus creating the internationally recognized standard nomenclature that had been noticeably lacking in the nineteenth century). Like many of these organizations, IUPAC was actually a reactivation of a prewar institution -in this case, the International Association of Chemical Societies, proposed in 1910 by Wilhelm Ostwald and Albin Haller, president of the French Chemical Society -but now with the Germans excluded. Cutting out the Germans implied cutting out German. German had been an official language, with English and French of the International Association; it was just obvious to the IRC's movers and shakers that it would not be permitted at IUPAC. Concern over the dominance of German, especially within chemistry, had been simmering for some time. ... In all these international venues, German was proscribed, and only (alongside Italian) granted a subsidiary status in IUPAC in 1929. ... In 1932, for example, French was permitted as an official language at 351 (98.5%) of the international conferences that year, and English was 298 (83.5%). The boycott being over, German was officially permitted at 60.5% -nothing to sneeze at, but a far cry from the parity one would have expected in the prewar years.
