Description

Ethyl 5-Acetyl-2-Amino-4,5,6,7-Tetrahydrothieno-[3,2-C]Pyridine-3-Carboxylate is a high-purity, advanced pharmaceutical intermediate with a complex heterocyclic structure. This compound is of significant value for its role as a key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly in therapeutic areas requiring sophisticated molecular scaffolds. It is primarily needed by research institutions, contract development and manufacturing organizations (CDMOs), and pharmaceutical companies engaged in the development of new chemical entities.

Application

• Pharmaceutical Intermediate: Serves as a critical precursor in the multi-step synthesis of complex drug candidates, especially those targeting central nervous system (CNS) disorders.
• Research & Development: Used in medicinal chemistry for structure-activity relationship (SAR) studies and the exploration of new pharmacophores within the tetrahydrothienopyridine class.
• API Synthesis: A key raw material in the production pipeline for potential APIs, where its specific acetyl and ester functional groups allow for further selective chemical modifications.
• Chemical Reference Standard: Supplied as a high-purity standard for analytical method development, validation, and quality control in pharmaceutical laboratories.
• Preclinical Studies: Utilized in the preparation of compounds for in vitro and in vivo biological testing during early-stage drug discovery.
