Description

2-Thiophenecarboxylicacid,5-Amino-3-Ethyl-,Ethylester(9Ci) CAS NO 766480-43-7 is a specialized heterocyclic building block featuring a thiophene core substituted with amino and ester functional groups. This compound matters for its role as a key intermediate in the synthesis of complex molecules, particularly in the pharmaceutical and agrochemical sectors. It is primarily needed by research chemists and process development scientists working on active pharmaceutical ingredients (APIs), advanced materials, and novel crop protection agents.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and other therapeutic areas.
• Agrochemical Synthesis: Used in the research and development of new pesticides and herbicides, leveraging its heterocyclic structure for biological activity.
• Material Science Research: Acts as a monomer or functionalizing agent in the development of conductive polymers and advanced organic electronic materials.
• Chemical Research & Development: Employed as a versatile scaffold in medicinal chemistry for structure-activity relationship (SAR) studies and library synthesis.
• Dye and Pigment Intermediate: Utilized in the synthesis of specialized dyes and pigments due to the chromophoric properties of the thiophene ring.
