The advancement of antiviral therapies hinges on the availability of specialized chemical intermediates that possess the precise structural and purity characteristics required for complex synthesis. Caronic Anhydride, identified by CAS number 67911-21-1 and molecular formula C7H8O3, has emerged as such a critical component, indispensable for the production of leading antiviral medications.

Primarily recognized for its role as a pharmaceutical intermediate, Caronic Anhydride serves as a key building block in the synthesis of Boceprevir, an oral protease inhibitor used to treat Hepatitis C. Its significance has further expanded with the advent of Paxlovid, Pfizer's potent oral antiviral for COVID-19, where Caronic Anhydride functions as a crucial starting material for a key structural fragment. This dual application highlights its importance in addressing significant global health challenges.

As a white solid with a typical purity of ≥99.0%, Caronic Anhydride's reliable quality is paramount for pharmaceutical manufacturers. Its specific physical properties, such as a melting point range of 53-57°C, are indicative of its well-defined chemical structure and suitability for demanding synthetic processes. For researchers and manufacturers aiming to buy this intermediate, partnering with a reputable manufacturer that guarantees these specifications is essential.
