Description

12-Oxo-12H-Benzo[G]Pyrido[2,1-B]Quinazoline-4-Carboxylic Acid is a high-purity, complex heterocyclic carboxylic acid derivative that serves as a critical advanced intermediate in organic synthesis. Its unique fused-ring structure makes it a valuable building block for the development of novel active pharmaceutical ingredients (APIs) and functional materials. This compound is primarily sought by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for its role in creating molecules with specific biological or photophysical properties.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel quinazoline-based drug candidates, particularly for applications in oncology and targeted therapies.
• Agrochemical Research: Used in the development of new-generation herbicides, fungicides, and plant growth regulators that leverage its complex heterocyclic core.
• Organic Light-Emitting Diodes (OLEDs): Serves as a potential electron-transport or emissive layer material due to its rigid, planar conjugated structure for advanced display technologies.
• Dye and Pigment Synthesis: Acts as a sophisticated intermediate for producing high-performance, color-fast organic dyes and functional pigments.
• Academic & Industrial R&D: Employed as a standard or novel scaffold in medicinal chemistry and material science research programs.
• Coordination Chemistry: The carboxylic acid group allows it to function as a ligand for metal complexes used in catalysis or as functional materials.
