Description

Isoxazolo[3,4-D]Pyridazine-4-Carboxylic Acid, 6-Ethyl-6,7-Dihydro-3-Methyl-7-Oxo- (9Ci) is a high-purity heterocyclic carboxylic acid derivative, serving as a critical advanced pharmaceutical intermediate. Its value lies in its complex fused-ring structure, which provides a versatile scaffold for synthesizing novel active pharmaceutical ingredients (APIs) with targeted biological activity. This compound is essential for research and development chemists in the pharmaceutical and agrochemical industries, particularly those focused on creating new therapeutic agents or crop protection solutions.

Application

• Pharmaceutical Intermediate: A key building block for the synthesis of novel drug candidates, particularly in medicinal chemistry research for central nervous system (CNS) or anti-infective agents.
• Agrochemical Research: Used as a precursor in the development of new herbicides, fungicides, or insecticides, leveraging its heterocyclic core.
• Chemical Synthesis Scaffold: Serves as a versatile starting material for further functionalization to create libraries of compounds for high-throughput screening.
• Academic & Contract Research: Employed in university and CRO (Contract Research Organization) laboratories for method development and structure-activity relationship (SAR) studies.
• Material Science Precursor: Potential use in the synthesis of specialized organic materials or ligands for catalytic systems.
