Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 396.49 g/mol gives Dexamethasone-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Dexamethasone-d4 (CAS 50-02-2(Unlabelled)), a certified reference material (molecular formula C22H25D4FO5, MW 396.49 g/mol) for analytical method development and quality control.
Based on its molecular formula C22H25D4FO5, Dexamethasone-d4 contains deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 396.49 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
