Chemical Structure

Epinastine Impurity 36 CAS CATO-C4X-184036 chemical structure

Description

Based on its molecular formula C14H14N2S, Epinastine Impurity 36 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 242.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

Epinastine Impurity 36 (CAS CATO-C4X-184036) is a certified pharmaceutical impurity reference standard with the molecular formula C14H14N2S and a molecular weight of 242.34 g/mol.

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.

CATO manufactures Epinastine Impurity 36 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.
