2-Methyl-7-oxo-4,7-dihydro-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylic Acid 98% Purity CAS 842954-97-6 Research Grade Fused Heterocyclic Building Bl

• • Product Overview

    2‑Methyl‑7‑oxo‑4,7‑dihydro‑[1,2,4]triazolo[1,5‑a]pyrimidine‑6‑carboxylic acid (CAS 842954‑97‑6) is a high‑purity fused heterocyclic building block featuring a triazolopyrimidine core. This compound is of significant interest in medicinal chemistry for the synthesis of kinase inhibitors, antiviral agents, and other biologically active molecules. It appears as an off‑white to pale yellow crystalline powder. Supplied at ≥98.0% purity as determined by HPLC, this research‑grade reagent is manufactured under strict quality control.

    Synthetic Process

    The synthesis typically involves the cyclization of appropriate aminotriazole precursors with dicarbonyl compounds, followed by carboxylation to introduce the carboxylic acid functionality.
