Selegiline EP Impurity D CAS 56862-28-3

Description

Compared with other compounds in its class, the molecular weight of 173.25 g/mol gives Selegiline EP Impurity D distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Selegiline EP Impurity D (CAS 56862-28-3), a pharmacopoeial impurity reference standard (molecular formula C12H15, MW 173.25 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C12H15, Selegiline EP Impurity D contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 173.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Selegiline EP Impurity D 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.
