Furazolidone stands out as a synthetic nitrofuran compound, widely recognized in both pharmaceutical and chemical industries. People remember it for its pronounced yellow appearance, usually found as a solid in either powdered or crystalline form. The formula for furazolidone reads C8H7N3O5, with a molecular weight of 225.16 g/mol. To get specific, this compound shows up as a pale yellow to orange powder and remains mostly odorless, dissolving in water at a limited rate, which shapes how folks work with it during formulation in labs or manufacturing environments.
Structurally, furazolidone consists of a nitrofuran ring fused to an oxazolidinone portion, connected through a methylene bridge. Chemical analysis reveals a density close to 1.5 g/cm³, making it heavier than many other pharmaceutical ingredients when measured by volume. Melting takes place between 254°C and 260°C, so it withstands transportation and processing at room temperature. On inspection, the compound does not emit significant vapors and maintains stability under usual storage conditions, sidestepping concerns about rapid degradation outside of very acidic or basic solutions.
Laboratories, chemical suppliers, and pharmaceutical manufacturers often prefer furazolidone in its solid state, shaped as powder, crystalline flakes, or sometimes fine pearls. Liquid solutions remain rare, mostly used in research settings where precise dosing or mixing is a priority. Quality control weighs moisture content and solubility in water or alcohol, since these direct processing outcomes for tablets, suspensions, or intermediate bulk materials. Because the compound resists clumping and does not react quickly with common excipients, handling proves straightforward, provided everyone wears gloves and eye protection.
Handling furazolidone safely requires attention. Research and regulatory insights say exposure should stay low, as the compound is flagged as hazardous and harmful to health. Repeated contact or inhalation causes irritation and can lead to potential toxicity, so proper storage and containment matter. The substance’s hazardous properties also trigger strict labeling – under the Globally Harmonized System (GHS), facilities assign it clear hazard classifications to keep people informed. Moving and storing the chemical calls for containers capable of protecting against light and moisture, as decomposed material can give off harmful byproducts. Disposal must align with regulatory frameworks, reflecting the need for environmental protection and occupational health.
Commodities like furazolidone get tracked globally through customs with a Harmonized System (HS) Code, which typically lands under 293499. The code standardizes trade and safety documentation, helping avoid shipment delays or compliance issues. Packaging always must counter potential leaks, while labeling lists molecular formula, hazard symbols, and batch details. Shipping lines and warehouse staff run periodic checks, using both visual inspection and chemical assays to prevent accidental exposure or contamination.
Chemical industries rely on furazolidone both as a raw material and a finished product. Its role in synthesis—particularly for antimicrobial, protozoacidal, and veterinary uses—derives from the property set of the nitrofuran group. In reaction vessels, it shows resilience, standing up to mixing with many solvents and not breaking down unless extreme heat or strong acid/alcohol environments are present. Manufacturers appreciate the predictable melting point, chemical resistance, and the limited solubility, all of which shape storage solutions and long-haul logistics.
Anyone who has handled furazolidone in real life understands the practical elements—keep it dry, follow safety labels, and limit airborne dust. Liquid forms appear in research tanks, usually mixed with alcohol or buffered water to keep concentrations consistent for accurate dosing. Powdered and crystalline furazolidone moves through hoppers and packaging lines without much hassle, but full-face protection and good ventilation keep workers safe. Once packed, sealed drums or cartons sit in climate-controlled storage away from food and heat sources, locking out both moisture and light to maintain potency.
