Xylometazoline EP Impurity B CAS 19387-83-8

Description

Compared with other compounds in its class, the molecular weight of 210.74 g/mol gives Xylometazoline EP Impurity B distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Xylometazoline EP Impurity B (CAS 19387-83-8), a pharmacopoeial impurity reference standard (molecular formula C13H19Cl, MW 210.74 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to chlorine substitution, an aromatic ring system, Xylometazoline EP Impurity B is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 210.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures Xylometazoline EP Impurity B under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
