Description

(E)-3-((R,2E,4E)-1-Hydroxy-4-methyl-6-((1S,2S,4R,6S,7R,8R)-1,2,7-trimethyl-5-oxo-3,9,10-trioxatricyclo[4.3.1.02,4]decan-8-yl)hepta-2,4-dien-1-ylidene)pyrrolidine-2,4-dione (CAS 34429-70-4) is a high-purity analytical reference standard with the molecular formula C22H27NO7 and a molecular weight of 417.45 g/mol.

Structurally, (E)-3-((R,2E,4E)-1-Hydroxy-4-methyl-6-((1S,2S,4R,6S,7R,8R)-1,2,7-trimethyl-5-oxo-3,9,10-trioxatricyclo[4.3.1.02,4]decan-8-yl)hepta-2,4-dien-1-ylidene)pyrrolidine-2,4-dione (C22H27NO7) contains a flavonoid core, an amide group, 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 417.45 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), (E)-3-((R,2E,4E)-1-Hydroxy-4-methyl-6-((1S,2S,4R,6S,7R,8R)-1,2,7-trimethyl-5-oxo-3,9,10-trioxatricyclo[4.3.1.02,4]decan-8-yl)hepta-2,4-dien-1-ylidene)pyrrolidine-2,4-dione 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.
