1-Bromooctene

Updated: 2026-08-11

Overview

1-Bromo-1-octene is a halogenated organic compound primarily used as an intermediate in chemical synthesis. Its molecular structure consists of an eight-carbon chain with a bromine atom attached to the terminal carbon, making it highly reactive in various organic reactions. This compound is typically a colorless to pale yellow liquid and is insoluble in water but miscible with common organic solvents. Due to its reactivity, 1-bromo-1-octene is widely employed in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals. Its applications extend to coupling reactions, where it serves as a key building block for more complex molecules. Proper handling is essential due to its corrosive and flammable nature.

Physical and Chemical Properties

1-Bromo-1-octene exhibits a density of approximately 1.13 g/cm³ and a boiling point range of 180-185°C. The compound is insoluble in water but dissolves readily in organic solvents such as ethanol, ether, and chloroform. Its molecular weight is 191.11 g/mol, and it appears as a colorless to pale yellow liquid under standard conditions. The bromine atom attached to the terminal carbon enhances its reactivity, making it suitable for nucleophilic substitution and elimination reactions. The compound's stability is influenced by storage conditions, and it should be kept away from light and heat to prevent decomposition or unwanted reactions.

Main Applications

1-Bromo-1-octene is predominantly used as an intermediate in organic synthesis. It plays a critical role in the production of pharmaceuticals, where it serves as a precursor for active pharmaceutical ingredients (APIs). Additionally, it is utilized in the agrochemical industry for synthesizing pesticides and herbicides. In specialty chemical manufacturing, this compound is valued for its ability to participate in cross-coupling reactions, such as the Heck reaction, to form carbon-carbon bonds. Its versatility also extends to the synthesis of fragrances and flavor compounds, where its reactive bromine group facilitates further functionalization.

Safety and Storage

1-Bromo-1-octene is classified as a hazardous substance due to its corrosive, irritant, and flammable properties. Proper personal protective equipment (PPE), including gloves, goggles, and lab coats, should be worn when handling this compound. Adequate ventilation is necessary to prevent inhalation of vapors. Storage should be in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources. Containers must be tightly sealed to prevent moisture ingress and volatilization. In case of spills, neutralize with appropriate absorbents and dispose of in accordance with local regulations.

B2B Procurement Guide

When procuring 1-bromo-1-octene, it is essential to verify the supplier's credentials and ensure they provide a Material Safety Data Sheet (MSDS). Bulk purchases may offer cost advantages, but proper packaging and transportation compliance are critical due to the compound's hazardous nature. Buyers should assess purity levels, typically ranging from 95% to 99%, depending on the application. Custom synthesis options may be available for specific requirements. Lead times and minimum order quantities (MOQs) vary, so early communication with suppliers is recommended to align with project timelines.
