Chemical Structure
Description
The occurrence of Heparin Disaccharide II-S Trisodium Salt is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Heparin Disaccharide II-S Trisodium Salt (CAS 136098-05-0) is a high-purity analytical reference standard with the molecular formula C12H16NO16S2Na and a molecular weight of 517.36 g/mol.
The molecular framework of Heparin Disaccharide II-S Trisodium Salt (C12H16NO16S2Na) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
