Chemical Structure
Description
The occurrence of 4-Methylumbelliferyl 2-Acetamido-2-deoxy-β-D-galactopyranoside 6-Sulfate Potassium Salt is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Methylumbelliferyl 2-Acetamido-2-deoxy-β-D-galactopyranoside 6-Sulfate Potassium Salt (CAS 383160-14-3), a certified reference material (molecular formula C18H20NO11SK, MW 497.51 g/mol) for analytical method development and quality control.
4-Methylumbelliferyl 2-Acetamido-2-deoxy-β-D-galactopyranoside 6-Sulfate Potassium Salt (C18H20NO11SK) contains a flavonoid core, an amide group, a sulfone group, 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).
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.
