Gatifloxacin stands out as a synthetic broad-spectrum antibacterial drug, known for its application in tackling various bacterial infections. Developed as a fourth-generation fluoroquinolone, it traces its impact from hospital settings all the way to research labs. White to pale yellow in appearance, gatifloxacin arrives in forms ranging from fine crystalline powders to solid flakes and pearls. Experience handling active pharmaceutical ingredients brings every chemist around to respect the importance of identifying true physical features—density, solubility, melting point, and even powder flow—because these points influence how a chemical behaves in preparation, blending, and administration.
This compound, built upon a bicyclic core typical of quinolones, brings the full might of modern chemistry into play. The molecular formula, C19H22FN3O4, marks a careful balance of carbon, hydrogen, nitrogen, fluorine, and oxygen, cementing its place in the fluoroquinolone class. Every molecular switch—in this case, the addition of fluorine at the C-6 position—sharply boosts antimicrobial activity. Weighing in with a specific molecular weight of 375.39 g/mol, gatifloxacin presents as a stable, crystalline solid at room temperature and is almost odourless, fitting right into protocols that demand precision and predictability.
Gatifloxacin crystals display a melting point hovering near 185°C. In the lab, solutions get prepared in pure or buffered water, as the solubility in common solvents runs moderate, sitting near 28 mg/mL at 25°C. Density approaches 1.56 g/cm³, ensuring powders pack tightly for compounding or bulk transport. Material safety data flags it as safe under strict handling—but not without certain caveats; exposure via inhalation or skin should stay limited, as with most raw chemical agents. The flakes and pearl forms allow for easier batching and dosing, especially during high-precision pharmaceutical manufacturing. As a solid, the compound remains stable in tightly sealed containers, shielded from moisture and light, as hydrolysis could threaten its chemical integrity. It does not come as a volatile or easily aerosolized solid, so labs often weigh and measure it in open air, provided basic health and safety precautions get observed.
The compound carries hazards common to quinolones. Regulatory agencies classify it as harmful upon ingestion or inhalation at high concentrations. Gatifloxacin acts on bacterial enzymes, but improper contact with skin or eyes causes irritation or, in some, allergic reactions. Storage recommendations require cool, dry spaces with access control and clear chemical labeling. Fire risk stays minimal since gatifloxacin is non-combustible, though its decomposition in extreme heat might release small amounts of nitrogen oxides or other toxic fumes. Protective clothing, gloves, and eye protection remain essential in all handling steps—from weighing raw material in the warehouse to precision compounding in the pharmaceutical clean room. Every shipment receives a Material Safety Data Sheet, speaking directly to regulatory mandates for transparency and end-user protection.
Customs and border agencies use HS code 29419090 for gatifloxacin, wrapping it within the spectrum of other antibacterial preparations. This coding simplifies global trade, speeds up compliance checks, and ensures the compound receives inspection and tracking expected for pharmaceutical raw materials. In my experience, reaching out to local authorities and customs brokers saves time during large-volume import, since guidelines differ from country to country. Every producer and dealer keeps certifications and lab assays handy, with a close watch on purity, batch number, and date of production. Shipments stay in sealed containers, with written notice of hazards and required controls for receiving facilities.
Like most fluoroquinolones, gatifloxacin’s therapeutic impact depends on careful dosing and awareness of possible side effects. Exposure and toxicity risks matter not only in patient care but also for chemical handlers and pharmaceutical engineers. Auditing storage conditions, maintaining up-to-date safety protocols, and conducting regular risk assessments can block accidental releases or mishandling that put people at risk. Beyond the lab, the growing problem of antibiotic resistance calls for responsible use—prescriptions only under fit conditions, in line with clinical guidelines, with robust record-keeping in pharmacies and facilities. Disposal of unused material must go through proper hazardous waste management, in compliance with local environmental laws.
In oral or ophthalmic formulations, gatifloxacin gets dissolved in solutions measured to the millilitre. Here, the purity and density of the crystalline form make direct impact on product performance and consistency. Formulators depend on accurate readings of solubility and specific gravity, as even small errors translate to subpar drug action or unexpected side effects. From raw chemical properties to finished pharmaceuticals, a close link ties the lab bench to the patient outcome. Looking back over years in chemical sourcing and logistics, just one missed safety step or confusion about molecular structure can trigger recalls or clinical failures, so attention to these hard material details does more than satisfy paperwork—lives depend on that precision.
