Description

2-Methyl-7-Oxo-3-Phenyl-4,7-Dihydro-Pyrazolo-[1,5-A]Pyrimidine-5-Carboxylic Acid is a high-purity, advanced pharmaceutical intermediate belonging to the pyrazolopyrimidine class of heterocyclic compounds. This compound is valued for its role as a critical building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly in therapeutic areas requiring complex molecular architectures. It is primarily sought by research institutions, custom synthesis firms, and pharmaceutical manufacturers engaged in drug discovery and development programs.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of complex drug candidates, especially those targeting kinase inhibition and other enzymatic pathways.
• Organic Synthesis Building Block: Used in medicinal chemistry for constructing fused heterocyclic systems with potential biological activity.
• Research & Development (R&D): Serves as a standard or starting material in academic and industrial research for exploring new chemical entities and structure-activity relationships (SAR).
• Custom Synthesis: Employed by contract research and manufacturing organizations (CROs/CMOs) for the production of bespoke compounds for client projects.
• Agrochemical Research: Potential application as an intermediate in the development of new agrochemicals due to its heterocyclic core.
