The pyrazole ring system is a foundational structure in medicinal chemistry, celebrated for its presence in a vast array of biologically active compounds. Among these, 4-Amino-1-methyl-3-propyl-1H-pyrazole-5-carboxamide, identified by CAS 139756-02-8, stands out not only as a crucial intermediate in the synthesis of Sildenafil citrate but also for its potential in broader scientific applications. As a high-purity white powder, it serves as a versatile building block for organic chemists, facilitating the creation of complex molecular structures essential for drug development and other chemical processes.

While its role in the pharmaceutical industry is primarily associated with the production of Sildenafil, a medication for erectile dysfunction and pulmonary arterial hypertension, the inherent properties of this pyrazole derivative suggest a wider scope of utility. Scientific literature points to its potential as a hypolipidemic agent, indicating its capacity to influence lipid metabolism, and as a possible phosphodiesterase 1 (PDE1) inhibitor. These emerging properties position 4-Amino-1-methyl-3-propyl-1H-pyrazole-5-carboxamide as a compound of interest for researchers investigating treatments for metabolic disorders and other conditions where PDE1 modulation is relevant.

For manufacturers and research institutions, securing a consistent supply of this intermediate is vital. Identifying a reputable 4-Amino-1-methyl-3-propyl-1H-pyrazole-5-carboxamide supplier, particularly from established chemical manufacturing hubs like China, ensures access to material that meets rigorous quality standards. Companies such as NINGBO INNO PHARMCHEM CO.,LTD. specialize in producing such fine chemicals, offering products with high purity (≥99%) and providing comprehensive technical data, including precise chemical and physical properties. Proper storage, often requiring refrigeration at -20°C, is essential to maintain the compound's integrity for these diverse applications.

The versatility of pyrazole scaffolds means that intermediates like 4-Amino-1-methyl-3-propyl-1H-pyrazole-5-carboxamide are not just limited to their most well-known applications. Their utility extends into various domains of chemical synthesis and discovery. Whether for established pharmaceutical production or cutting-edge research into new therapeutic avenues, the reliable availability of high-quality 4-Amino-1-methyl-3-propyl-1H-pyrazole-5-carboxamide is a critical factor for success. By partnering with trusted chemical manufacturers, the scientific community can continue to leverage the unique properties of these compounds for innovation.
