Overview
4-Bromo-1-butene is an organobromine compound primarily used as a building block in organic synthesis. Its molecular structure features a bromine atom attached to the terminal carbon of a butene chain, making it a versatile reagent for nucleophilic substitution reactions. This compound is particularly valuable in pharmaceutical and agrochemical manufacturing, where it serves as an intermediate for more complex molecules. Due to its reactivity, it must be handled with care under controlled conditions to prevent undesired reactions or hazards.
Physical and Chemical Properties
4-Bromo-1-butene is a colorless to pale yellow liquid with a characteristic pungent odor. It has a density of 1.31 g/cm³ and a boiling point range of 100-102 °C, making it relatively volatile at room temperature. The compound is highly soluble in common organic solvents such as ethanol, ether, and acetone but exhibits negligible solubility in water. Its reactivity stems from the labile bromine atom, which readily participates in substitution reactions, including Grignard and Suzuki couplings.
Main Applications
The primary use of 4-bromo-1-butene is as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals. It is a key precursor for compounds like 4-aminobutene, which finds applications in drug development. In agrochemicals, it is employed to create herbicides and pesticides. Additionally, its role in polymer chemistry includes modifying polymer chains to introduce functional groups, enhancing material properties for industrial applications.
Safety and Storage
Due to its flammability and corrosive nature, 4-bromo-1-butene requires strict safety measures. Storage should be in tightly sealed containers, away from heat sources and oxidizing agents, in a cool, well-ventilated area. Personal protective equipment (PPE) such as gloves, goggles, and lab coats are mandatory during handling. Spills should be neutralized with inert absorbents and disposed of as hazardous waste, following local regulations.
B2B Procurement Guide
When procuring 4-bromo-1-butene, buyers should prioritize suppliers with ISO or GMP certifications to ensure quality and consistency. Request a Certificate of Analysis (COA) for each batch to verify purity, typically ≥98% for industrial use. Bulk purchases (e.g., 25 kg drums) often reduce costs, but storage capacity must align with usage rates to prevent degradation. For international shipments, confirm compliance with transportation regulations for hazardous chemicals.
