Chemical Structure
Description
Structurally, 126485-47-0 ACMC-20dj70 Benzoic acid,4-hydroxy-3,5-dimethoxy-,(2,3,4,4a,6,10b-hexahydro-3,4,8,10-tetrahydroxy-9-methoxy-6-oxopyrano[3,2-c][2]benzopyran-2-yl)methylester, [2R-(2a,3b,4a,4aa,10bb)]- (9CI) (C23H24O13) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 508.43 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).
126485-47-0 ACMC-20dj70 Benzoic acid,4-hydroxy-3,5-dimethoxy-,(2,3,4,4a,6,10b-hexahydro-3,4,8,10-tetrahydroxy-9-methoxy-6-oxopyrano[3,2-c][2]benzopyran-2-yl)methylester, [2R-(2a,3b,4a,4aa,10bb)]- (9CI) (CAS 126485-47-0), molecular formula C23H24O13 and molecular weight 508.43 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
