Description

Benorilate CAS NO 5003-48-5 is a pharmaceutical compound that functions as a prodrug of both acetylsalicylic acid (aspirin) and paracetamol (acetaminophen). This unique dual-action profile makes it a valuable intermediate for developing analgesic and antipyretic medications. It is primarily required by pharmaceutical manufacturers and research institutions engaged in the synthesis of novel therapeutic agents or generic drug formulations.

Application

• Pharmaceutical Intermediate: Key starting material or intermediate in the synthesis of analgesic and antipyretic drug products.
• Research & Development: Used in pharmacological studies to develop new combination drug therapies with improved efficacy or safety profiles.
• Analgesic Prodrug Synthesis: Serves as a precursor in the manufacturing of prodrugs designed for targeted drug delivery and reduced gastrointestinal side effects.
• Reference Standard: Employed as an analytical standard in quality control laboratories for method development and validation.
• Chemical Synthesis: Utilized in organic synthesis for creating novel ester-linked molecular entities.

Quality Control

Our Benorilate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) that detail specifications and results for key parameters such as assay, related substances, and residual solvents, supporting compliance with cGMP and ICH guidelines for pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light exposure to maintain stability and purity.
