Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, Dexamethasone 21-Palmitate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 630.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Dexamethasone 21-Palmitate (CAS 14899-36-6) is a high-purity analytical reference standard with the molecular formula C38H59FO6 and a molecular weight of 630.87 g/mol.
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), Dexamethasone 21-Palmitate 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.
