Estradiol Valerate EP Impurity F CAS 18069-79-9

Description

The occurrence of Estradiol Valerate EP Impurity F is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Estradiol Valerate EP Impurity F (CAS 18069-79-9) is a certified pharmaceutical impurity reference standard with the molecular formula C22H30O3 and a molecular weight of 342.47 g/mol.

Structurally, Estradiol Valerate EP Impurity F (C22H30O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 342.47 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), Estradiol Valerate EP Impurity F meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
