Desloratadine-d5 CAS 1020719-34-9

Description

Compared with other compounds in its class, the molecular weight of 315.85 g/mol gives Desloratadine-d5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Desloratadine-d5 (CAS 1020719-34-9), a certified reference material (molecular formula C19H14D5ClN2, MW 315.85 g/mol) for analytical method development and quality control.

The molecular framework of Desloratadine-d5 (C19H14D5ClN2) is characterized by deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Desloratadine-d5 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.
