Posaconazole is a sophisticated antifungal agent whose chemical structure and properties enable its potent therapeutic action. As a triazole derivative, its molecular formula is C37H42F2N8O4, with a molecular weight of approximately 700.78 g/mol. The compound exists as a white to off-white powder, a characteristic that is important for its handling and formulation. Understanding the Posaconazole chemical properties is fundamental for its effective use in pharmaceutical manufacturing.

The CAS number for Posaconazole is 171228-49-2, a unique identifier crucial for regulatory compliance and global trade. This number is essential for any entity looking to source high-quality Posaconazole API. The compound is known for its high purity, typically 99%, which is a testament to advanced manufacturing processes.

The primary application of Posaconazole is its potent antifungal activity. It functions as a sterol C14α demethylase inhibitor, a targeted triazole antifungal mechanism that disrupts fungal cell membrane integrity. This mechanism makes it effective against a broad spectrum of fungi, including Aspergillus and Candida species, and some Zygomycetes. Its application extends to treating invasive aspergillosis, oropharyngeal candidosis, and other serious fungal infections like chromoblastomycosis and mycetoma.

Furthermore, Posaconazole plays a critical role in prophylaxis, preventing invasive fungal infections in immunocompromised individuals. For patients undergoing chemotherapy or stem cell transplantation, this preventative measure is often life-saving. The appropriate posaconazole oral suspension dosage ensures optimal therapeutic levels for both treatment and prophylaxis.

For pharmaceutical companies and researchers, knowing where to buy Posaconazole is a key consideration. Sourcing from a reliable Posaconazole CAS 171228-49-2 supplier is essential to guarantee the quality and consistency of the API. The availability of Posaconazole in powder form allows for diverse formulation strategies, catering to various patient needs and delivery methods.

In summary, Posaconazole is a chemically robust and therapeutically vital antifungal agent. Its well-defined properties and diverse applications, from treating resistant infections to providing crucial prophylaxis, underscore its importance in modern medicine. Reliable sourcing of this API is fundamental to its continued impact on patient health.
