Description

Compared with other compounds in its class, the molecular weight of 344.36 g/mol gives (3aS,4R,6R,11aR)-6-Methyl-3,10-dimethylene-2,7-dioxo-2,3,3a,4,5,6,7,10,11,11a-decahydro-6,9-epoxycyclodeca[b]furan-4-yl methacrylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3aS,4R,6R,11aR)-6-Methyl-3,10-dimethylene-2,7-dioxo-2,3,3a,4,5,6,7,10,11,11a-decahydro-6,9-epoxycyclodeca[b]furan-4-yl methacrylate (CAS 133559-38-3) is a high-purity analytical reference standard with the molecular formula C19H20O6 and a molecular weight of 344.36 g/mol.

Structurally, (3aS,4R,6R,11aR)-6-Methyl-3,10-dimethylene-2,7-dioxo-2,3,3a,4,5,6,7,10,11,11a-decahydro-6,9-epoxycyclodeca[b]furan-4-yl methacrylate (C19H20O6) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 344.36 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (3aS,4R,6R,11aR)-6-Methyl-3,10-dimethylene-2,7-dioxo-2,3,3a,4,5,6,7,10,11,11a-decahydro-6,9-epoxycyclodeca[b]furan-4-yl methacrylate 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.
