Chemical Structure

Tegoprazan Impurity 57 CAS 1640981-02-7 chemical structure

Description

The occurrence of Tegoprazan Impurity 57 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tegoprazan Impurity 57 (CAS 1640981-02-7) is a certified pharmaceutical impurity reference standard with the molecular formula C18H20N2O4 and a molecular weight of 328.36 g/mol.

The molecular framework of Tegoprazan Impurity 57 (C18H20N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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 Tegoprazan Impurity 57 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.
