Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 364.48 g/mol gives 20-alpha-Dihydro Cortisol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
20-alpha-Dihydro Cortisol (CAS 1719-79-5) is a high-purity analytical reference standard with the molecular formula C21H32O5 and a molecular weight of 364.48 g/mol.
Structurally, 20-alpha-Dihydro Cortisol (C21H32O5) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 364.48 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures 20-alpha-Dihydro Cortisol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
