Chemical Structure
Description
Eszopiclone-d8 (CAS 1093385-24-0) is a high-purity analytical reference standard with the molecular formula C17H9D8ClN6O3 and a molecular weight of 396.86 g/mol.
Eszopiclone-d8 (C17H9D8ClN6O3) contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Eszopiclone-d8 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.
