1-Bromobutane stands out as a colorless liquid, often used as a chemical intermediate in organic synthesis and industrial manufacturing. Its molecular formula, C4H9Br, lays out a structure with a four-carbon butane backbone and a bromine atom attached to the terminal carbon. The boiling point hovers near 101 °C, while the density settles at about 1.273 g/cm³ at 20 °C. This density, higher than water’s, tells you something essential about how it behaves during separation and purification. Out on the bench or scale, 1-Bromobutane’s mild, sweet odor signals volatility, making ventilation and containment important for health and safety reasons.
This compound leaves a slick residue on glass or metal. It’s not one you confuse for water, oil, or other domestic liquids. As an alkyl halide, 1-Bromobutane reacts strongly with nucleophiles, and this chemical reactivity underpins its value in Grignard reactions or as a starting point in laboratory syntheses. Anyone who has handled it knows its solubility limits: 1-Bromobutane does not mix well with water, forming two distinct layers if added together. This separation has real advantages and headaches. It simplifies washes during extraction, but it means spills won’t dilute easily. Safety goggles and gloves matter in daily handling, whether in powder traces on benchtops or droplets leaking from glassware.
Look closely at the structure and you’ll see linear symmetry. The butyl chain extends straight, offering fewer steric conflicts than branched isomers. The molecular weight lands at about 137.02 g/mol. For international trade and global supply chains, 1-Bromobutane falls under the HS Code 29033990, an identifier that controls its movement and tracks duties or safety regulations in customs databases. Purity often clocks in at 98% or above, required for most synthetic routes and applications.
In practice, 1-Bromobutane ships and stores almost exclusively as a liquid. The idea of this compound showing up as flakes, solid, powder, pearls, or crystal runs against practical experience. With a melting point at −112 °C, naturally, you rarely see a solid phase outside specialized low-temperature labs. Liquefaction and density make bulk transport in drums or jugs safe when proper containment and temperature controls stick to protocol.
Safety teams treat 1-Bromobutane with respect because of its flammability and health concerns. Eye or skin contact causes irritation, while vapor inhalation can trigger headaches or central nervous system effects. Long-term industrial workers will remember the importance of fume hoods, chemical splash goggles, proper ventilation, and chemical-resistant gloves. Spills or leaks require prompt sand containment and solvent-compatible cleanup pads. Storage away from heat sources, open flames, and oxidizing agents prevents accidents. The safety data sheets describe its GHS symbol for harmful and flammable substances, underlining the need for careful risk assessments. In emergency rooms, benzyl bromide’s cousin 1-Bromobutane would be handled with similar caution—no shortcuts or casual exposure tolerated.
Industry puts 1-Bromobutane to work as a building block for pharmaceuticals, flavors, fragrances, and other specialty chemicals. In a plant mixing hall, you’ll see it funneled into reactors, not poured by hand but delivered using closed transfer systems to avoid risk. Raw material quality impacts yield and product safety downstream, so batch-to-batch consistency matters. It is not just a “feedstock”—its trace impurities can cause side reactions, influencing everything from color to stability of drugs or intermediates. Cost and supply fluctuations ripple through procurement offices; anyone in sourcing monitors commodity price changes, supply routes, and regulatory controls. In the United States and Europe, regulations demand strict documentation, transport labeling, and environmental controls. These rules don’t choke off use but create a safer environment for workers and end-users.
Disposal remains a core concern. Pouring 1-Bromobutane down the drain fouls waterways and risks regulatory fines. Waste must go into approved chemical containers, scheduled for safe destruction or recycling by certified hazardous waste services. Environmental protection means isolating spills fast, training all staff, and not cutting corners to save time. Chronic exposure can affect health, so ongoing air monitoring and health checks are standard in responsible operations. Learning from past incidents, the industry puts a premium on preparedness and safe material handling—nobody forgets a close call with volatile chemicals.
Looking for solutions means targeting safer alternatives, closed system engineering, and better personal protective equipment. Some labs choose green chemistry approaches to cut reliance on halogenated compounds. Improved labeling, real-time leak detection, and regular safety training help lower risk on the floor. Teams who track incidents and near-misses write better protocols. For suppliers and buyers alike, updates to the global harmonized system keep everyone informed about the newest handling guidelines or legislative changes.
Trust builds when users see commitment to clear labeling, high purity, accurate specifications, and reliable regulatory compliance. Professional experience proves that corners shaved on documentation or safety breed trouble. Reliable suppliers, detailed batch certificates, and a track record of safe delivery mean the most to those directly responsible for safety and efficiency. 1-Bromobutane, from its physical behavior to industrial usage, demands vigilance and respect—ensuring that harm to people or the planet gets minimized isn’t an abstract goal, but a routine part of responsible chemical handling and application.
