Chemical Structure

Desalkyl Ebastine-d5 CAS 1189424-36-9 chemical structure

Description

The molecular framework of Desalkyl Ebastine-d5 (C18H16D5NO) is characterized by deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Desalkyl Ebastine-d5 (CAS 1189424-36-9), molecular formula C18H16D5NO and molecular weight 272.40 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), Desalkyl Ebastine-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.
