Chemical Structure
Description
CATO supplies Heparin Disaccharide I-S Tetrasodium Salt (CAS 136098-10-7), a certified reference material (molecular formula C12H15NO19S3Na, MW 596.41 g/mol) for analytical method development and quality control.
The molecular framework of Heparin Disaccharide I-S Tetrasodium Salt (C12H15NO19S3Na) 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).
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.
