Description

3-Allyl-2-Mercapto-5,6,7,8-Tetrahydro-3H-Benzo[4,5]Thieno[2,3-D]Pyrimidin-4-One is a high-purity, advanced pharmaceutical intermediate characterized by its unique fused heterocyclic structure. This compound matters for its critical role as a key building block in the synthesis of complex active pharmaceutical ingredients (APIs), particularly in therapeutic areas requiring sophisticated molecular scaffolds. Pharmaceutical R&D teams and fine chemical manufacturers need this material for developing next-generation drug candidates, where its specific functional groups enable targeted chemical modifications.

Application

• Pharmaceutical Intermediate: Serves as a core scaffold for the research and development of novel drug candidates, particularly in central nervous system (CNS) and oncology therapeutic areas.
• Chemical Synthesis Building Block: Utilized in organic synthesis for constructing complex heterocyclic systems due to its reactive allyl and mercapto functional groups.
• Research & Development (R&D): Essential for medicinal chemistry programs in academic, institutional, and industrial laboratories exploring new chemical entities.
• Precursor for API Manufacturing: Used in the multi-step synthesis of target Active Pharmaceutical Ingredients (APIs) under current Good Manufacturing Practice (cGMP) conditions.
• Ligand and Catalyst Development: Potential application in designing novel ligands for catalytic systems or metal-organic frameworks (MOFs).

Quality Control

Our 3-Allyl-2-Mercapto-5,6,7,8-Tetrahydro-3H-Benzo[4,5]Thieno[2,3-D]Pyrimidin-4-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical R&D and synthesis. Certificates of Analysis (COA) detailing batch-specific results are available upon request, supporting your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep the container tightly sealed in a dry environment to minimize exposure to moisture.
