Chemical Structure
Description
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.
4-Methylumbelliferyl N-N-N-N-tetraacetyl-β-D-chitotetraoside (CAS 53643-14-4) is a high-purity analytical reference standard with the molecular formula C42H60N4O23 and a molecular weight of 988.94 g/mol.
4-Methylumbelliferyl N-N-N-N-tetraacetyl-β-D-chitotetraoside (C42H60N4O23) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
