Chemical Structure
Description
The occurrence of Lansoprazole EP Impurity E is closely related to a nitrile group, sulfur-containing functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Lansoprazole EP Impurity E (CAS 583-39-1) is a certified pharmaceutical impurity reference standard with the molecular formula C7H6N2S and a molecular weight of 150.20 g/mol.
The molecular framework of Lansoprazole EP Impurity E (C7H6N2S) is characterized by a nitrile group, sulfur-containing functionality, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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 Lansoprazole EP Impurity E 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.
