Description

Erythromycinstinoprate CAS NO 84252-03-9 is a macrolide antibiotic derivative, specifically a stinoprate salt form of erythromycin. This compound is valued for its enhanced stability and bioavailability compared to the base erythromycin, making it a critical intermediate in advanced pharmaceutical synthesis. It is primarily required by manufacturers in the pharmaceutical industry for the development and production of specialized antibiotic formulations.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of advanced macrolide antibiotic APIs (Active Pharmaceutical Ingredients).
• Veterinary Medicine Production: Used in formulating antibiotics for treating bacterial infections in livestock and companion animals.
• Research & Development: Serves as a reference standard and building block in microbiological and pharmacological research.
• Controlled-Release Formulations: Employed in the development of sustained-release oral dosage forms due to its modified physicochemical properties.
