Description

4(3H)-Quinazolinone, 7-Chloro-2-[(Ethylamino)Methyl]- is a specialized heterocyclic organic compound that serves as a crucial advanced intermediate in modern synthetic chemistry. Its unique quinazolinone scaffold, functionalized with chloro and ethylaminomethyl groups, makes it a valuable building block for constructing complex molecules with targeted biological activity. This high-purity intermediate is primarily sought by research institutions and pharmaceutical companies engaged in the development of new active pharmaceutical ingredients (APIs) and agrochemicals.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders, anti-inflammatory agents, and kinase inhibitors.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and plant growth regulators due to its bioactive quinazolinone core.
• Chemical Biology & Proteomics: Serves as a scaffold for designing molecular probes and enzyme inhibitors to study biological pathways.
• Material Science Research: Investigated as a monomer or additive for creating specialty polymers with unique optical or electronic properties.
• Academic & Contract Research: Essential for methodological development and discovery chemistry in university and CRO (Contract Research Organization) laboratories.
