Cortisone-d8 CAS 1257650-98-8 chemical structure

Description

Cortisone-d8 (CAS 1257650-98-8) is a high-purity analytical reference standard with the molecular formula C21H20D8O5 and a molecular weight of 368.49 g/mol.

Based on its molecular formula C21H20D8O5, Cortisone-d8 contains deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 368.49 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Cortisone-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.
