Chemical Structure

Testosterone Impurity N11 CAS 3275-64-7 chemical structure

Description

The molecular framework of Testosterone Impurity N11 (C20H32O) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Testosterone Impurity N11 (CAS 3275-64-7) is a certified pharmaceutical impurity reference standard with the molecular formula C20H32O and a molecular weight of 288.47 g/mol.

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), Testosterone Impurity N11 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.
