Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 288.30 g/mol gives Irenolone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Irenolone (CAS 149184-19-0), molecular formula C19H12O3 and molecular weight 288.30 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Irenolone (C19H12O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 288.30 g/mol, it falls into the medium-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), Irenolone 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.
