Description

Fuzlocillin is a semi-synthetic penicillin derivative with a broad spectrum of antibacterial activity. Its primary value lies in its enhanced stability and efficacy against a range of Gram-positive and Gram-negative bacteria, making it a critical intermediate in advanced pharmaceutical synthesis. This compound is essential for manufacturers in the pharmaceutical industry developing next-generation antibiotic formulations and for research institutions conducting microbiological studies.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of potent antibiotic APIs (Active Pharmaceutical Ingredients).
• Research & Development: Used in microbiological and pharmacological research to study bacterial resistance mechanisms and develop new therapeutic agents.
• Veterinary Medicine: Employed in the formulation of antibacterial treatments for livestock and companion animals.
• Reference Standard: Utilized as a high-purity analytical standard for quality control and regulatory testing in pharmaceutical laboratories.

Quality Control

Our Fuzlocillin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, residual solvent analysis, and microbiological examination, to ensure it meets stringent standards suitable for pharmaceutical applications. Certificates of Analysis (COA) documenting full compliance are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation.
