Description

Gatifloxacinacid CAS NO 121577-32-0 is a key pharmaceutical intermediate and the active carboxylic acid form of the broad-spectrum fluoroquinolone antibiotic, Gatifloxacin. This compound is critical for ensuring the quality and efficacy of the final active pharmaceutical ingredient (API) used in ophthalmic and systemic antibacterial formulations. It is primarily required by pharmaceutical manufacturers, research institutions, and fine chemical suppliers engaged in the synthesis of advanced antibiotic drugs.

Application

• Pharmaceutical Intermediate: Primary building block for the synthesis of the antibiotic Gatifloxacin API.
• Active Pharmaceutical Ingredient (API) Manufacturing: Used in the final production stages of Gatifloxacin for ophthalmic solutions and tablets.
• Research & Development: Serves as a critical reference standard and starting material in antimicrobial research and new drug development.
• Fine Chemical Synthesis: Utilized in the preparation of novel fluoroquinolone derivatives and analogs for biological testing.
• Quality Control & Analytical Standards: Employed as a high-purity standard in HPLC and other analytical methods for assay and impurity profiling.

Quality Control

Our Gatifloxacinacid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification (IR, HPLC), assay (HPLC), and control of related substances and residual solvents to ensure it meets high-purity standards suitable for pharmaceutical use. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

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.
