About Dinoprostone EP Impurity C (Free Base)

Dinoprostone EP Impurity C (Free Base) is a pharmacopeial impurity of Alprostadil carrying the CAS registry number 36150-00-2. The compound has the formula C20H32O5, corresponding to a molecular weight of 352.5 g/mol. Systematically, it is named (E)-7-[(1R,2R,3R)-3-hydroxy-2-[(E,3S)-3-hydroxyoct-1-enyl]-5-oxocyclopentyl]hept-5-enoic acid. It is also known as Alprostadil - Impurity H or Dinoprostone EP Impurity C.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Pharmaceutical QC and development laboratories use this impurity standard of Alprostadil to develop and validate HPLC methods, to set specification limits and to document impurity profiles in ANDA and DMF submissions. It is used across pharmaceutical manufacturing and academic and industrial research.

We offer Dinoprostone EP Impurity C (Free Base) in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
