D-Xylose Standard | CAS 58-86-6 |
High-Purity Reference Material

D-xylose is widely used in the D-xylose absorption test, a diagnostic tool for evaluating intestinal function and malabsorption syndromes. By administering a known dose of D-xylose and measuring its excretion in urine or concentration in blood, clinicians can assess the ability of the small intestine to absorb monosaccharides. A high-purity D-xylose standard ensures accurate calibration of test methods and reliable patient results.

A certified reference material (CRM) provides guaranteed purity, traceability, and batch-to-batch consistency, which are critical for reproducible results in regulated environments such as pharmaceuticals, clinical laboratories, and food testing. Regular chemical-grade D-xylose may contain impurities or lack documentation, which can compromise analytical reliability.

D-xylose can be analyzed using HPLC, GC, LC-MS, and spectrophotometric methods. It is particularly important in carbohydrate profiling, metabolic flux analysis, and bioenergy research. Using a standard ensures accurate quantification and method validation.

D-xylose standards should be stored at room temperature in a dry environment, protected from humidity and light. Improper storage may lead to degradation or moisture absorption, which can affect purity and analytical performance. Sealed containers with desiccants are recommended for long-term stability.

D-Xylose Standard is produced under strict ISO/IEC 17025 and GMP-compliant procedures to ensure exceptional purity, traceability, and consistency.
Unlike regular laboratory-grade D-Xylose, which may contain variable levels of impurities, our standard comes with a Certificate of Analysis (COA), Safety Data Sheet (SDS), and batch-specific traceability information.
This guarantees reliable, reproducible results in calibration, method validation, and quality control testing. For regulated industries like pharmaceuticals, food and beverage, and clinical diagnostics, using certified reference materials is critical for regulatory compliance and audit readiness.

D-Xylose Standard is compatible with a broad range of analytical techniques used in modern laboratories, including:

• HPLC (High-Performance Liquid Chromatography) – for sugar quantification and purity analysis.

• GC (Gas Chromatography) – for volatile carbohydrate derivates.

• LC-MS / GC-MS (Mass Spectrometry) – for complex biological and food matrix analysis.

• UV/Vis Spectrophotometry – for basic quantitative analysis.

Because of its high purity (≥95%), it ensures consistent calibration and helps laboratories minimize baseline noise and improve detection accuracy, which is especially important for high-throughput testing environments.
