Description

Purine CAS NO 120-73-0 is a fundamental heterocyclic aromatic organic compound, serving as the core structural framework for adenine and guanine, the two purine bases found in DNA and RNA. Its significance lies in its role as a critical building block and intermediate in the synthesis of pharmaceuticals, agrochemicals, and nucleoside analogs. This high-purity compound is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical industries.

Application

• Pharmaceutical Intermediate: A key starting material for synthesizing antiviral drugs (e.g., acyclovir), anticancer agents, and other nucleoside-based therapeutics.
• Biochemical Research: Used as a standard and precursor in metabolic pathway studies, enzyme inhibition assays, and nucleic acid research.
• Agrochemical Synthesis: Serves as an intermediate in the production of certain herbicides and plant growth regulators.
• Fine Chemical Production: Employed in the manufacture of dyes, photographic chemicals, and other specialty organic compounds.
• Nucleoside & Nucleotide Synthesis: Fundamental scaffold for the chemical and enzymatic production of modified nucleosides and nucleotides.
• Academic & Industrial R&D: Critical for discovery chemistry and process development in life sciences.
