Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 301.34 g/mol gives Labetalol Impurity 64 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Labetalol Impurity 64 (CAS CATO-C4X-246664) is a certified pharmaceutical impurity reference standard with the molecular formula C17H19NO4 and a molecular weight of 301.34 g/mol.
The molecular framework of Labetalol Impurity 64 (C17H19NO4) 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 Labetalol Impurity 64 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.
