Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (-)-bursehernin (3R,4R)-4-(1,3-benzodioxol-5-ylmethyl)-3-(3,4-dimethoxybenzyl)dihydrofuran-2(3H)-one (3R-trans)-4-(1,3-benzodioxol-5-ylmethyl)-3-[(3,4-dimethoxyphenyl)methyl]dihydro-2(3H)-furanone (R,R)-4-(1,3-benzodioxol-5-ylmethyl)-3-(3,4-dimethoxybenzyl)dihydrofuran-2(3H)-one 40456-51-7 CHEBI:90893 bursehernin.

(-)-bursehernin (3R,4R)-4-(1,3-benzodioxol-5-ylmethyl)-3-(3,4-dimethoxybenzyl)dihydrofuran-2(3H)-one (3R-trans)-4-(1,3-benzodioxol-5-ylmethyl)-3-[(3,4-dimethoxyphenyl)methyl]dihydro-2(3H)-furanone (R,R)-4-(1,3-benzodioxol-5-ylmethyl)-3-(3,4-dimethoxybenzyl)dihydrofuran-2(3H)-one 40456-51-7 CHEBI:90893 bursehernin (CAS 40456-51-7) is a high-purity analytical reference standard with the molecular formula C21H22O6 and a molecular weight of 370.40 g/mol.

(-)-bursehernin (3R,4R)-4-(1,3-benzodioxol-5-ylmethyl)-3-(3,4-dimethoxybenzyl)dihydrofuran-2(3H)-one (3R-trans)-4-(1,3-benzodioxol-5-ylmethyl)-3-[(3,4-dimethoxyphenyl)methyl]dihydro-2(3H)-furanone (R,R)-4-(1,3-benzodioxol-5-ylmethyl)-3-(3,4-dimethoxybenzyl)dihydrofuran-2(3H)-one 40456-51-7 CHEBI:90893 bursehernin (C21H22O6) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
