Technical Description

Xylohexaose (CAS 49694-21-5), also known as 1,4-β-D-Xylohexaose (DP6), is a high-purity linear hexasaccharide. It is produced by Shaanxi Sunrise Pharmaceutical through enzymatic hydrolysis of premium corn-derived xylan followed by multi-stage chromatographic purification.

As a primary reference standard, it is essential for the kinetic characterization of xylanases, prebiotic fermentation profiling, and as a quantitative marker in complex dietary fiber analysis using HPAEC-PAD or LC-MS platforms.

Technical FAQ

1. Why is Xylohexaose (DP6) difficult to detect with standard HPLC-UV?

Carbohydrates like Xylohexaose lack chromophores, meaning they do not absorb UV light. We recommend using ELSD (Evaporative Light Scattering Detector), RI (Refractive Index), or HPAEC-PAD for accurate detection.

2. Is this product suitable for in vivo animal studies?

While high-purity (≥98%), this is a research-grade standard. It is intended for laboratory assays. If required for pilot animal metabolic studies, please contact us for specific batch endotoxin/microbial data.

3. Can Xylohexaose be dissolved in Ethanol for sample preparation?

No. Xylohexaose has very poor solubility in anhydrous ethanol. For best results and high recovery, Ultrapure Water is the mandatory solvent.

4. What is the difference between Xylohexaose and Xylo-oligosaccharide (XOS) mixtures?

Commercial XOS is a mixture of DP2-DP7. Our Xylohexaose is a monomeric standard (DP6), providing a single peak for precise quantitative calibration and specific enzyme-substrate binding studies.

5. How do you ensure the structural integrity of the β-(1→4) bonds?

Every batch undergoes 1H-NMR and 13C-NMR analysis to confirm the specific glycosidic linkage and the degree of polymerization (DP6), ensuring zero contamination from other sugars.
