Ph. Eur. Grade (European Pharmacopoeia) chemicals

Material that complies with its European Pharmacopoeia monograph, binding across the Ph. Eur. member states.

What the grade means

Ph. Eur. grade material complies with its monograph in the European Pharmacopoeia, published by the European Directorate for the Quality of Medicines and HealthCare (EDQM) of the Council of Europe. The texts are legally binding in all states that have signed the European Pharmacopoeia Convention, a group wider than the European Union. A new edition appears every three years, with supplements in between.

EP is a common abbreviation for the pharmacopoeia, but some reagent catalogues use it for extra pure. Zemixal writes Ph. Eur. to avoid that confusion.

What a monograph controls

  • Definition, content and characters.
  • Identification and related substances, often with named specified impurities.
  • Residual solvents, elemental impurities, water and sulfated ash.
  • Assay and, for excipients, functionality-related characteristics.

When to choose it

Choose Ph. Eur. grade for medicines registered in Europe and in markets that accept European texts. A CEP from EDQM can support the API section of a dossier.

Documentation

Each lot ships with a COA naming the edition or supplement, plus a GHS SDS. Specified impurities are available from Impurity Reference Standards.

Questions

About Ph. Eur. Grade (European Pharmacopoeia)

Is a Ph. Eur. monograph the same as a BP monograph?
For substances covered by the European Pharmacopoeia, the BP reproduces the Ph. Eur. text, so the requirements are identical. The BP also contains national monographs that have no Ph. Eur. equivalent.
What are specified impurities in a Ph. Eur. monograph?
They are named impurities with individual limits, listed in the transparency statement of the monograph. Laboratories need reference materials for them to identify and quantify each one.
Does the COA need to state the Ph. Eur. supplement?
It should state the edition, and ideally the supplement, that applies. Monographs can change between supplements, and auditors check that testing followed the version in force.
