Chemical Structure
Description
The occurrence of Hydrocortisone 17-Valerate is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Hydrocortisone 17-Valerate (CAS 57524-89-7), molecular formula C26H38O6 and molecular weight 446.58 g/mol, is a CATO reference standard with documented purity and traceability.
Hydrocortisone 17-Valerate (C26H38O6) contains a steroid 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 17-Valerate 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.
