Description

9-β-D-Ribofuranosyladenine Hemisulfate Salt is a high-purity nucleoside derivative, essential as a critical building block and reference standard in advanced biochemical research and pharmaceutical development. Its primary value lies in providing a stable, well-defined form of the adenosine riboside moiety, crucial for studying nucleoside metabolism, enzyme kinetics, and nucleic acid chemistry. This compound is particularly needed by researchers and manufacturers in the fields of pharmaceutical intermediates, antiviral/anticancer drug discovery, and diagnostic reagent production.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel nucleoside-based therapeutics, including antiviral and anticancer agents.
• Biochemical Research: Used as a substrate or inhibitor in enzymatic studies, particularly those involving kinases, phosphorylases, and other nucleoside-metabolizing enzymes.
• Reference Standard: Acts as a high-purity analytical standard for quality control and method validation in HPLC, LC-MS, and NMR analyses within QC/QA laboratories.
• Diagnostic Reagent Development: Employed in the formulation of diagnostic kits and assays that detect or quantify enzymatic activity related to purine metabolism.
• Academic Research: Fundamental tool for studying RNA synthesis, modification, and the biochemical pathways of adenosine and its derivatives.
