Overview
1-Bromobutane, commonly referred to as industrial grade bromobutane, is an alkyl halide with significant applications in chemical synthesis. As a four-carbon chain with a bromine substituent, it serves as a versatile building block in organic chemistry. Industrial grade bromobutane typically has a purity of 98-99% and is distinguished from laboratory or reagent grades by its larger volume packaging and cost-effectiveness for industrial applications. It's particularly valued in bulk chemical operations where consistent quality and reliable supply are paramount.
Physical and Chemical Properties
1-Bromobutane presents as a colorless to slightly yellow liquid with a characteristic sweet odor. Its relatively high density (1.276 g/cm³) makes it heavier than water. The compound's low melting point (-112°C) and moderate boiling point (101-102°C) make it suitable for various reaction conditions. Chemically, 1-bromobutane is reactive with strong oxidizers and bases. It undergoes typical alkyl halide reactions including nucleophilic substitutions and eliminations. The bromine atom's good leaving group ability makes it valuable for creating carbon-carbon bonds in synthesis applications.
Main Applications
In the pharmaceutical industry, 1-bromobutane serves as a key intermediate for producing various active pharmaceutical ingredients (APIs). It's particularly useful in the synthesis of quaternary ammonium compounds and other nitrogen-containing pharmaceuticals. The agrochemical sector utilizes 1-bromobutane in the production of pesticides and herbicides. Additionally, it finds use as a solvent in specialty applications and as an alkylating agent in organic synthesis for creating longer carbon chains or more complex molecular structures.
Safety and Storage
As a flammable liquid, 1-bromobutane requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, goggles, and proper ventilation. Storage areas should be equipped with explosion-proof electrical equipment and proper fire suppression systems. Containers should be kept tightly closed and protected from physical damage. In case of spills, absorb with inert material and dispose of properly. The compound is stable under recommended storage conditions but may decompose when exposed to extreme heat, producing toxic fumes including hydrogen bromide.
B2B Procurement Guide
When sourcing industrial grade 1-bromobutane, verify the supplier's quality control processes and request certificates of analysis. Bulk purchases (typically 200kg drums or isotanks) generally offer better pricing, but consider your storage capabilities and usage rate. Evaluate suppliers based on their production capacity, logistics capabilities, and regulatory compliance. Established chemical manufacturers with ISO certification are generally preferred. Consider establishing long-term supply agreements with price adjustment mechanisms to manage cost volatility.
