Description

D-(+)-Xylose is a high-purity pentose sugar, a fundamental building block in carbohydrate chemistry. This enantiomerically pure compound is essential for research and industrial processes requiring defined stereochemistry and consistent quality. It is a critical raw material and reference standard for the pharmaceutical, food science, and biotechnology industries, where precise molecular structure impacts product performance and regulatory compliance.

Application

• Pharmaceutical Intermediate: Used in the synthesis of nucleoside analogs, antiviral drugs, and other active pharmaceutical ingredients (APIs).
• Microbiological Media & Diagnostics: Serves as a selective carbon source in culture media for identifying specific bacterial strains, such as in clinical diagnostics.
• Food & Flavor Industry: Acts as a precursor for flavor compounds (e.g., furfural) and a low-calorie sweetener or bulking agent in specialized dietary products.
• Biochemical Research: Employed as a substrate in enzymatic studies, metabolic pathway analysis, and carbohydrate metabolism research.
• Chiral Building Block: Utilized in asymmetric synthesis to introduce chirality into more complex organic molecules for agrochemicals and fine chemicals.
• Cell Culture & Fermentation: Provides a defined carbohydrate source in mammalian and microbial cell culture processes and fermentation broths.

Quality Control

Our D-(+)-Xylose is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and food-grade applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and handling properties.
