Naphazoline EP Impurity D Hydrochloride CAS 6028-15-5

Description

Compared with other compounds in its class, the molecular weight of 246.74 g/mol gives Naphazoline EP Impurity D Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Naphazoline EP Impurity D Hydrochloride (CAS 6028-15-5), a pharmacopoeial impurity reference standard (molecular formula C14H14N2HCl, MW 246.74 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Naphazoline EP Impurity D Hydrochloride (C14H14N2HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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 246.74 g/mol, it falls into the medium-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), Naphazoline EP Impurity D Hydrochloride 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.
