Description
CATO supplies 21233-18-1 (1,1'-Biphenyl)-2-carboxylic acid, 3,3',5-trihydroxy-, 2-ester with 5-ethenyl-6-(beta-D-glucopyranosyloxy)-4,4a,5,6-tetrahydro-4a-hydroxy-1H,3H-pyrano(3,4-c)pyran-1-one, (4aR-(4aalpha,5beta,6alpha))- Gentiopicroside (CAS 21233-18-1), a certified reference material (molecular formula C29H30O14, MW 602.54 g/mol) for analytical method development and quality control.
21233-18-1 (1,1'-Biphenyl)-2-carboxylic acid, 3,3',5-trihydroxy-, 2-ester with 5-ethenyl-6-(beta-D-glucopyranosyloxy)-4,4a,5,6-tetrahydro-4a-hydroxy-1H,3H-pyrano(3,4-c)pyran-1-one, (4aR-(4aalpha,5beta,6alpha))- Gentiopicroside (C29H30O14) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
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.
