3'-Sialyllactose sodium salt, min. 90 %, 100 mg

3'-Sialyllactose sodium salt is a biochemical reagent supplied at a minimum purity of 90 %, with CAS number 128596-80-5 and empirical formula C₂₃H₃₈NO₁₉Na. The molar mass is 655,53 g/mol. This sodium salt of the sialylated trisaccharide is offered in a 100 mg pack size for laboratory-scale weighing, stock preparation and experimental work in chemical and biochemical research. The defined carbohydrate structure and stated assay support use wherever a characterised 3'-sialyllactose salt is required as a reference, standard or starting material. Identity data covering CAS registry number, empirical formula and molar mass facilitate inventory control, documentation and concentration calculations. The product is available from manufacturer Carl ROTH within its biochemicals portfolio and is suited to analytical method development, glycoscience studies and related bench applications that specify this oligosaccharide sodium salt. Clear labelling of purity and molecular parameters helps laboratories maintain traceable records when preparing solutions or comparing lots. The compact 100 mg unit is practical for method scouting and small-series experiments without excess material on hand.
