What is Sparfloxacin powder?
Headquartered in Xi'an, the historic origin of the ancient Silk Road, Xi'an Faithful BioTech Co., Ltd. takes full advantage of the city's robust logistics and chemical industrial resources to develop into a comprehensive fine chemical supplier serving clients worldwide. Sparfloxacin powder, CAS No. 110871-86-8, is a third-generation fluoroquinolone fine chemical antibacterial raw material with the molecular formula C₁₉H₂₂F₂N₄O₃ and a relative molecular mass of 392.40. It appears as a pale yellow crystalline powder at room temperature and possesses a stable quinoline carboxylic acid cyclic molecular structure. Its core mechanism of action is to target and inhibit bacterial DNA gyrase activity, blocking the replication, transcription, and repair processes of microbial genetic material, thereby inhibiting the proliferation of harmful bacteria at its source. Its mechanism of action differs from that of β-lactam antibacterial agents, therefore it can still exert a significant inhibitory effect on strains resistant to β-lactams. Based on its stable physicochemical properties and clear antibacterial mechanism, this compound is widely used in the field of microbiology laboratories. It is often used as a standard reference for scientific research experiments such as screening of new antibacterial raw materials, evaluation of strain sensitivity, and quantitative detection of antibacterial activity. At the same time, it is also an important intermediate in the field of fine chemical synthesis. The industry will optimize its water solubility and permeability through salt-forming modification processes, and derive a variety of activity-modified derivatives to expand its adaptability in microbial control-related research and development scenarios.
Sparfloxacin powder Manufacturing Process
From a chemical production perspective, Sparfloxacin powder can be prepared on a large scale through multi-step aromatic ring fluorination and condensation ring-closing reactions. The purity of the finished product can be improved to scientific research standards through recrystallization and chromatographic purification processes. It should be stored in a light-proof and sealed container to avoid structural decomposition caused by strong light and to ensure the long-term stability of its antibacterial activity.

Mechanism of action of Sparfloxacin powder
Inhibition of microbial DNA gyrase: Hinders the entanglement and unwinding of bacterial DNA, blocking normal replication of genetic material.
Inhibition of topoisomerase IV: Interferes with microbial chromosome segregation, preventing the division and proliferation of progeny cells.
Synergistic effect of dual enzyme inhibition: Simultaneously acts on two key enzymes, significantly reducing the probability of microorganisms developing tolerance traits.
Blocking gene transcription: Disrupts the nucleic acid template, inhibits the synthesis of harmful microbial proteins, and limits bacterial population expansion.
