Chemical Structure
Description
The occurrence of Prednisolone-D6 is closely related to deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Prednisolone-D6 (CAS CATO-C4X-191930) is a high-purity analytical reference standard with the molecular formula C21H22D6O5 and a molecular weight of 366.48 g/mol.
Prednisolone-D6 (C21H22D6O5) contains deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
