Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 368.51 g/mol gives Drospirenone EP Impurity I distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Drospirenone EP Impurity I (CAS 2896199-04-3) is a certified pharmaceutical impurity reference standard with the molecular formula C24H32O3 and a molecular weight of 368.51 g/mol.
Structurally, Drospirenone EP Impurity I (C24H32O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 368.51 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Drospirenone EP Impurity I under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
