Description

Sparfloxacin CAS NO 110871-86-8 is a synthetic broad-spectrum fluoroquinolone antibiotic known for its potent activity against a wide range of Gram-positive and Gram-negative bacteria, including atypical pathogens. Its primary commercial value lies in its critical role as a high-purity active pharmaceutical ingredient (API) for the formulation of advanced antibacterial medications. This compound is essential for pharmaceutical manufacturers and research institutions developing treatments for respiratory, urinary tract, and other serious bacterial infections, ensuring therapeutic efficacy and product quality.

Application

• Pharmaceutical API: Primary use as the active ingredient in the manufacture of antibacterial tablets, capsules, and injectable formulations.
• Veterinary Medicine: Utilized in the development of antibacterial treatments for livestock and companion animals.
• Clinical Research: Serves as a reference standard and key intermediate in pharmacological and microbiological studies.
• Antibacterial Drug Development: A crucial building block for synthesizing new fluoroquinolone derivatives and combination therapies.
• Microbiological Testing: Used in laboratory settings for antibiotic susceptibility testing and quality control of culture media.

Quality Control

Our Sparfloxacin is manufactured under strict quality management systems to meet the rigorous standards of the pharmaceutical industry. Every batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling via advanced techniques like HPLC. A Certificate of Analysis (COA) is provided with each shipment, detailing compliance with in-house specifications. While not currently certified to a specific pharmacopoeia, production follows current Good Manufacturing Practice (cGMP) principles to ensure consistency, traceability, and reliability for our global B2B clients.

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 after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
