Chemical Structure

Alpha-Hydroxy Metoprolol-d5 (Mixture of Diastereomers) CAS 1189934-03-9 chemical structure

Description

The molecular framework of Alpha-Hydroxy Metoprolol-d5 (Mixture of Diastereomers) (C15H20D5NO4) is characterized by deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Alpha-Hydroxy Metoprolol-d5 (Mixture of Diastereomers) (CAS 1189934-03-9), molecular formula C15H20D5NO4 and molecular weight 288.39 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Alpha-Hydroxy Metoprolol-d5 (Mixture of Diastereomers) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
