The International Union of Pure and Applied Chemistry (IUPAC / ˈ aɪ juː p æ k, ˈ juː-/) is an international federation of National Adhering Organizations working for the advancement of the chemical sciences, especially by developing nomenclature and terminology.

iupac跨部門的命名及符號委員會（iupac命名法）是建立化學元素及化合物命名標準的國際權威。 自從創立以來，IUPAC由多個委員會運行，各有其能 [ 6 ] 。

In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended [1] [2] by the International Union of Pure and Applied Chemistry (IUPAC).

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 ...

iupac有机物命名法是一种有系统命名有机化合物的方法。 该命名法是由 國際純粹與應用化學聯合會 （IUPAC）规定的，最近一次修订是在1993年。 其前身是1892年日内瓦国际化学会的“系统命名法”。

The International Union of Pure and Applied Chemistry (IUPAC) is an international organisation that represents chemists in individual countries. It governs everything to do with chemicals, elements and new discoveries.

The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC). IUPAC Nomenclature ensures that each compound (and its various isomers) have only one formally accepted name known as the systematic IUPAC name.

The International Union of Pure and Applied Chemistry (IUPAC) has published four sets of rules to standardize chemical nomenclature. There are two main areas: IUPAC nomenclature of inorganic chemistry (Red Book)
