Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 366.48 g/mol gives Hydrocortisone-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Hydrocortisone-d4 (CAS 73565-87-4) is a high-purity analytical reference standard with the molecular formula C21H26D4O5 and a molecular weight of 366.48 g/mol.
Based on its molecular formula C21H26D4O5, Hydrocortisone-d4 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 366.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Hydrocortisone-d4 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.
