1,2-dibromoethane

CAS: 106-93-4

Overview

1,2-Dibromoethane (CAS 106-93-4 ), also known as EDB and ethylene bromide, is a brominated organic compound used industrially as a chemical intermediate and flame retardant precursor.

Historically significant as a soil and grain fumigant, its agricultural use is now heavily restricted or banned in many jurisdictions, shifting commercial relevance toward polymer and specialty chemical manufacturing.

In plastics and polymer systems, it functions as a reactive intermediate in the synthesis of flame retardant additives, contributing bromine content to formulations targeting fire performance standards.

EDB serves as a key alkylating and brominating agent in the production of specialty organic compounds, including pharmaceutical and agrochemical intermediates for various industrial applications.

In leaded fuel systems, it was historically compounded with lead scavengers to prevent engine deposit buildup, though this application is now obsolete in most global markets today.

Residual demand exists in controlled laboratory and industrial synthesis where its reactivity profile supports specific halogenation reactions required for complex chemical manufacturing processes.

1,2-Dibromoethane is supplied as a liquid in drums or IBC containers. Technical grade is the standard commercial specification, with purity levels typically at 98% or higher.

Procurement is subject to regulatory controls in many regions, and buyers should verify import and handling compliance before sourcing this material for their specific industrial needs.
