5-Dehydroepisterol CAS 23582-83-4

Description

Compared with other compounds in its class, the molecular weight of 396.65 g/mol gives 5-Dehydroepisterol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Dehydroepisterol (CAS 23582-83-4), molecular formula C28H44O and molecular weight 396.65 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-Dehydroepisterol (C28H44O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 396.65 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 5-Dehydroepisterol 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.
