In the intricate world of chemical synthesis and pharmaceutical development, the quality of starting materials and intermediates is paramount. For research scientists and procurement managers, identifying reliable sources for high-purity heterocyclic compounds can significantly impact the success of their projects. One such crucial intermediate is 2-Amino-5,6-dihydro-4H-cyclopenta[b]thiophene-3-carbonitrile, identified by its CAS number 70291-62-2. This molecule serves as a foundational building block in numerous organic chemistry applications, particularly in the creation of novel pharmaceutical agents.

Understanding the specifications of such intermediates is the first step towards effective sourcing. 2-Amino-5,6-dihydro-4H-cyclopenta[b]thiophene-3-carbonitrile, with its molecular formula C8H8N2S and a molecular weight of 164.22800, is characterized by its solid form and a light brown to brown appearance. Key physical properties include a melting point of 153-154°C, a boiling point of 379.9°C at 760 mmHg, and a flash point of 183.6°C. Crucially, it is typically available with a purity of 95% minimum, density of 1.33 g/cm3, and a refractive index of 1.649. Its stability under normal temperatures and pressures makes it a manageable compound for synthesis and storage, often recommended to be kept in a cool, dry, well-ventilated area away from incompatible substances.

For organizations looking to buy this vital intermediate, exploring partnerships with established chemical manufacturers and suppliers is essential. Proximity and reliability are key considerations. When sourcing from China, for instance, diligent vetting of suppliers ensures not only competitive pricing but also adherence to quality standards. Companies that offer comprehensive technical data, free samples, and responsive customer service are typically preferred. This allows researchers to confirm the suitability of the compound for their specific synthetic pathways without upfront commitment.

The demand for such specialized heterocyclic intermediates is driven by the continuous innovation in drug discovery and material science. As R&D pipelines expand, the need for efficient and trustworthy chemical supply chains grows. For procurement professionals, developing relationships with global chemical providers who can consistently deliver high-quality products like 2-Amino-5,6-dihydro-4H-cyclopenta[b]thiophene-3-carbonitrile (CAS: 70291-62-2) is a strategic advantage. This ensures that research projects can proceed without interruption, ultimately accelerating the development of new and improved products across various industries.
