For procurement managers and R&D scientists in the pharmaceutical sector, identifying and sourcing critical raw materials like Caronic Anhydride (CAS 67911-21-1) is a cornerstone of successful drug development. This compound, with its molecular formula C7H8O3, plays a vital role as a pharmaceutical intermediate, particularly in the creation of life-saving antiviral medications.

The primary application of Caronic Anhydride lies in its use as a precursor for synthesizing key fragments of antiviral drugs. It is instrumental in the production of Boceprevir, an important oral treatment for Hepatitis C, and has also emerged as a crucial starting material for Paxlovid, Pfizer's orally administered antiviral medication for COVID-19. The demand for these therapies underscores the importance of a stable supply chain for high-quality Caronic Anhydride.

When looking to buy Caronic Anhydride, pharmaceutical buyers prioritize purity, consistency, and reliability. With a typical assay of ≥99.0%, this white solid intermediate ensures that downstream synthesis steps proceed efficiently and yield the desired active pharmaceutical ingredients (APIs) with high integrity. Understanding the typical properties, such as a melting point between 53-57°C, is also essential for quality control.
