This revised general chapter applies to all individual monographs as of 1 January 2023.

As mentioned in the General Notices, ‘General chapters become mandatory when referred to in a monograph, unless the wording clearly indicates that it is not the intention to make the text referred to mandatory but rather to cite it for information.’

The fact that a Ph. Eur. general chapter (e.g. 2.2.46) is referred to in another Ph. Eur. general chapter (e.g. 2.2.29. Liquid chromatography), does not render it mandatory as such, unless the other general chapter (2.2.29 in our example) is referred to in a given Ph. Eur. monograph.
