Chemical Structure

Vardenafil Impurity N2 CAS 448184-54-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 449.48 g/mol gives Vardenafil Impurity N2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Vardenafil Impurity N2 (CAS 448184-54-1), a pharmacopoeial impurity reference standard (molecular formula C19H23N5O6S, MW 449.48 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Vardenafil Impurity N2 (C19H23N5O6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 449.48 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Vardenafil Impurity N2 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.
