Hydrates Database

The hydrates database contains all pharmaceuticals monographed in the European Pharmacopeia (Pharmacopeia Europa 6.2, 2012) and collates information about known hydrates of these drug substances as well as links where relevant experimental data can be found. If there is no hydrate data under a particular entry then it is because we are not aware that it forms a hydrate - please update us if ay are missing. Note that the database includes reported hydrates even where there is no crystallographic data and so it complements other resources such as the Cambridge Structural Database.

Click on the headings to sort the columns as you wish. If you want to search by stoichiometry or by hydrate type please use the search function on the right or our detailed search interface.
