Based on its molecular formula C31H52N2O23, 3'-SLeX 3'-Sialyl-Lewis X 3'-Sialyl-Lewis-X tetrasaccharide 98603-84-0 D-Glucose, O-(N-acetyl-a-neuraminosyl)-(2>3)-O-b-D-galactopyranosyl-(1>4)-O-[6-deoxy-a-L-galactopyranosyl-(1>3)]-2-(acetylamino)-2-deoxy- (9CI) D-glucose, O-5-(acetylamino)-3,5-dideoxy-D-glycero-alpha-D-galacto-2-nonulopyranonosyl-(2>3)-O-beta-D-galactopyranosyl-(1>4)-O-[6-deoxy-alpha-L-galactopyranosyl-(1>3)]-2-(acetylamino)-2-deoxy- SLex SSEA 1 Sialyl Lex tri Sialyl-Lewis X a-NeuNAc-(2>3)-b-D-Gal-(1>4)(a-L-Fuc-[1>3])-D-GlcNAc contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 820.74 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
