Description
Nimodipine EP Impurity C (CAS 70172-96-2) is supplied by ImpurityLab as a European Pharmacopoeia impurity standard, identified by letter against the monograph for its parent substance. Catalogue number C4X-13853. It is related to Nimodipine.
The material is issued against molecular formula C21H26N2O8, molecular weight 434.44 g mol−1, physical form described as pale yellow solid.
Structural notation: C1(=C(C(OCCOC)=O)C(C2=CC=CC([N+](=O)[O-])=C2)C(C(OCCOC)=O)=C(C)N1)C
Letter designations are assigned inside a monograph for one named substance. The same molecule can carry a different letter, or a different style of name, in another pharmacopoeia. Map the material from its structure — chemical name, formula and CAS — rather than from the letter alone.
Storage. Store at 2-8 °C. Allow the container to reach room temperature before opening so that moisture does not condense onto the material. Record the date of first opening on the label.
Pack sizes. 1 mg / 10 mg / 25 mg / 50 mg / 80 mg / 100 mg / 200 mg. Non-standard quantities are quoted on request, normally within two working days.
Documentation. Each lot is released with a certificate of analysis that states the assay method, the water content and the form as supplied. The safety data sheet is available with the same lot number. Quote catalogue number C4X-13853 when requesting either document.
Documentation
Documents are issued per lot. The COA you receive describes the lot that ships, not a representative sample.
Regulatory reference
EP Impurity C. Confirm the acceptance criterion, the reporting threshold and the edition of the monograph against your own method before use.
