1,4-β-D-Xylopentaose, min. 95 %, 5 mg

1,4-β-D-Xylopentaose is a pentasaccharide biochemical supplied at a minimum purity of 95 %, with CAS number 49694-20-4 and empirical formula C₂₅H₄₂O₂₁. The molar mass is 678,59 g/mol, enabling accurate preparation of standards and assay solutions. Manufacturer Carl ROTH provides the material as part of its biochemical assortment for research environments. The β-1,4-linked xylose structure makes it relevant for investigations of hemicellulases, substrate specificity and oligosaccharide profiling. Explicit CAS registration and molecular formula support traceable documentation in method validation and publication-ready experiments. The small pack size matches specialised assays where only limited quantities of a defined xylopentaose are required. Researchers can use the compound for chromatographic calibration, mass-spectrometric comparison or kinetic evaluation of carbohydrate-active enzymes. Maintain appropriate laboratory controls when handling the solid reagent.
