Chemical Structure
Description
CATO supplies D-(+)-Raffinose undecaacetate (CAS 6424-12-0), a certified reference material (molecular formula C40H54O27, MW 966.84 g/mol) for analytical method development and quality control.
D-(+)-Raffinose undecaacetate (C40H54O27) 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.
