D-Galactose-4-O-sulphate sodium, min. 95 %, 5 mg

D-Galactose-4-O-sulphate sodium is a sulphated monosaccharide derivative offered at min. 95 % with empirical formula C₆H₁₂O₉SNa and molar mass 283,21 g/mol (CAS number 125113-68-0). The compound is Position of the sulphate at the 4-O site makes this sodium salt a useful model compound for investigating sulphation patterns, lectin interactions and synthetic routes to sulphated galactose analogues. Laboratories employ it as a reference material in chromatographic method development, mass-spectrometric characterisation and small-scale conjugation or enzymatic assays. The defined purity level and molecular formula support reproducible experimental design where authentic 4-O-sulphated galactose is required. Material from manufacturer Carl ROTH is intended for research environments handling fine biochemicals and carbohydrate standards. The low milligram quantity matches screening, calibration and exploratory synthesis needs without excess inventory. Applications include studies of glycosaminoglycan-related motifs, sulphotransferase substrates and analytical standards for sulphated hexoses in academic and industrial settings.
