General Description

Dibromomethane (CAS 74-95-3), also known as methylene bromide, is a halogenated methane derivative. It shows up as a colorless fluid with a pleasurable odor. It is slightly soluble in water and denser than water.

Dibromomethane is made use of mostly as a solvent in organic synthesis and as an intermediate in the production of specialty chemicals, agrochemicals, and pharmaceuticals. It is also employed as a gauge fluid and in the conversion of polyols to methylenedioxy by-products. Furthermore, it functions as an extractant in logical chemistry for determining details environmental pollutants.

We are among the three largest makers of dibromomethane worldwide, with a yearly output of 4000MT. Our items are mainly offered to South Korea, Japan, and Southeast Asia.

Product Applications

Dibromomethane is utilized in a range of applications across various fields:

Chemical Synthesis:

  • Intermediate: Dibromomethane works as an intermediate in the synthesis of drugs, agrochemicals, and various other organic compounds. It’s especially valuable in processes where a dihalomethane is needed for introducing bromine atoms right into a particle.
  • Reagent: It functions as a reagent in organic chemistry for different makeovers, consisting of nucleophilic substitutions and the development of carbon-bromine bonds.

Flame Retardants:

Additive: It is made use of as an additive in flame resistants for plastics and fabrics, boosting their resistance to ignition and combustion. Its efficiency is because of the bromine atoms which aid in satiating free radicals during burning.


Extraction and Cleaning: Dibromomethane is employed as a solvent in the removal of certain chemicals and in cleansing applications where its non-flammability and capability to liquify a selection of compounds are advantageous.


Fumigant: In the past, dibromomethane was made use of as a fumigant and chemical.

Properties of Dibromomethane

Dibromomethane exhibits several notable physical and chemical properties:

Physical State: It is a colorless liquid at room temperature.

Molecular Weight: 173.83 g/mol.

Density: Approximately 2.477 g/cm³ at 25°C, indicating its high density compared to water.

Boiling Point: 96-98°C, which is relatively low, contributing to its volatility.

Melting Point: -52°C, making it liquid at a wide range of temperatures.

Solubility: It is moderately soluble in water (4.3 g/L at 25 ° C) and miscible with organic solvents such as ethanol, ether, and chloroform.

Reactivity: Dibromomethane is steady under regular conditions yet can disintegrate when subjected to high temperatures or light, potentially launching bromine gas. It responds with bases and strong oxidizers, and it can join halogenation and replacement reactions.

Why Use Dibromomethane?

Dibromomethane is a versatile chemical with considerable applications in organic synthesis, fire retardants, solvents, and previously in chemicals. Its properties, including high density, moderate water solubility, and reactivity, make it valuable in different industrial procedures.
