Description

Xylocytidine CAS NO 3530-56-1 is a modified nucleoside analog of cytidine, where the ribose sugar is replaced by a xylose moiety. This structural modification is of significant interest in biochemical and pharmaceutical research, particularly in the study of nucleoside metabolism, antiviral drug development, and as a building block for oligonucleotide synthesis. It serves as a critical intermediate and research tool for scientists in medicinal chemistry, molecular biology, and pharmacology. Our supply ensures high purity and batch-to-batch consistency to support rigorous R&D and production processes.

Application

• Pharmaceutical Intermediate: Key starting material or intermediate in the synthesis of novel antiviral and anticancer nucleoside analogs.
• Biochemical Research: Used as a substrate or inhibitor in enzymatic studies to investigate nucleoside kinase and metabolic pathways.
• Oligonucleotide Synthesis: Serves as a modified building block (phosphoramidite) for the solid-phase synthesis of antisense oligonucleotides or aptamers with altered properties.
• Metabolic Pathway Studies: A tool compound for probing the role of sugar modifications in cellular uptake and anabolism of nucleosides.
• Reference Standard: Used as an analytical standard in HPLC or LC-MS for quality control and method development in pharmaceutical analysis.

Quality Control

Every batch of Xylocytidine is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high standards required for research and development. A detailed Certificate of Analysis (COA) is supplied with each shipment, reporting key parameters such as purity (HPLC), identity (IR, NMR), and impurity profile. Our quality protocols are designed to support compliance with cGMP and ISO guidelines where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
