Description

Lascufloxacin is a synthetic broad-spectrum fluoroquinolone antibiotic, distinguished by its potent activity against a wide range of Gram-positive and Gram-negative bacteria. Its primary value lies in its enhanced efficacy against respiratory pathogens, including drug-resistant strains, making it a critical active pharmaceutical ingredient (API) for advanced therapeutic formulations. This compound is essential for pharmaceutical manufacturers and research institutions developing next-generation antibacterial treatments, particularly for respiratory tract infections, skin and soft tissue infections, and ophthalmic solutions.

Application

• Active Pharmaceutical Ingredient (API) in the formulation of oral tablets and capsules.
• Key component in the development of injectable antibiotic solutions for systemic infections.
• Primary agent in ophthalmic solutions and ointments for treating bacterial eye infections.
• Research and development of novel antibacterial drugs targeting multi-drug resistant organisms.
• Intermediate in the synthesis of more complex fluoroquinolone derivatives.
• Reference standard for quality control and analytical testing in pharmaceutical laboratories.

Quality Control

Our Lascufloxacin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity pharmaceutical-grade specifications, typically exceeding 98.5% purity by HPLC. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with identity, purity, and impurity profile requirements. We support cGMP standards for API production to ensure consistency and reliability for our global pharmaceutical partners.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which may affect stability and potency. Long-term storage under inert atmosphere (e.g., nitrogen) is recommended.
