Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (+)-alpha-viniferin (2R,2aR,7R,7aR,12S,12aS)-2,7,12-tris(4-hydroxyphenyl)-2,2a,7,7a,12,12a-hexahydrobis[1]benzofuro[3',4':4,5,6;3'',4'':7,8,9]cyclonona[1,2,3-cd][1]benzofuran-4,9,14-triol 62218-13-7 CHEBI:66359 alpha-viniferin.
(+)-alpha-viniferin (2R,2aR,7R,7aR,12S,12aS)-2,7,12-tris(4-hydroxyphenyl)-2,2a,7,7a,12,12a-hexahydrobis[1]benzofuro[3',4':4,5,6;3'',4'':7,8,9]cyclonona[1,2,3-cd][1]benzofuran-4,9,14-triol 62218-13-7 CHEBI:66359 alpha-viniferin (CAS 62218-13-7), molecular formula C42H30O9 and molecular weight 678.68 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (+)-alpha-viniferin (2R,2aR,7R,7aR,12S,12aS)-2,7,12-tris(4-hydroxyphenyl)-2,2a,7,7a,12,12a-hexahydrobis[1]benzofuro[3',4':4,5,6;3'',4'':7,8,9]cyclonona[1,2,3-cd][1]benzofuran-4,9,14-triol 62218-13-7 CHEBI:66359 alpha-viniferin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 678.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
