Chemical Structure
Description
D-Glucosamine-2-N-3-O-disulphate disodium salt (CAS 112898-34-7) is a high-purity analytical reference standard with the molecular formula C6H11NO11S2Na and a molecular weight of 360.26 g/mol.
Based on its molecular formula C6H11NO11S2Na, D-Glucosamine-2-N-3-O-disulphate disodium salt contains a carbohydrate-derived structure, an amide group, a sulfone group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 360.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
