1,4-Dichlorobutane
1,4-Dichlorobutane is the difunctional four-carbon building block used as raw material and solvent for organic synthesis, including adiponitrile and carboxymethyl drug routes. It is supplied as a clear colourless liquid at 99.59% minimum assay by GC with moisture at 0.059% maximum.
What You Get With This Grade
- Assay 99.59% minimum by GC, the tightest purity figure in our halogenated range
- Moisture 0.059% maximum by Karl Fischer
- Two reactive chloride ends, which is what makes the ring and chain extension chemistry possible
- 180 kg drums or tank truck, packed to user requirement
Technical features
- Clear colourless liquid
- Difunctional with chloride at both ends of a four-carbon chain
- Assay determined by gas chromatography
- Moisture determined by Karl Fischer titration
Where 1,4-Dichlorobutane Is Used
Adiponitrile synthesis
Used in the synthesis of adiponitrile as a named route.
Pharmaceutical intermediates
Applied in carboxymethyl drug synthesis.
General organic synthesis
Serves as raw material and solvent for organic synthesis.
Chain extension chemistry
The 1,4-difunctionality provides a four-carbon spacer between two nucleophiles.
Buyers This Grade Is Built For
- Nylon intermediate producers working adiponitrile routes
- API manufacturers needing a difunctional four-carbon linker
- Fine chemical plants requiring high assay difunctional halides
- Buyers who specify assay to two decimal places
What It Stops Going Wrong
- Monofunctional impurities in a difunctional halide cap the chain and kill the yield
- Moisture in a dichloride hydrolyses one end before the second substitution happens
- Assay stated as 99% rather than 99.59% hides where the impurity budget sits
- DG shipment planning has to happen before the container is booked

What We Can Change
Drum or tank truck packing according to user requirements.
Against the Alternatives
1,4-Dichlorobutane is the only difunctional halide in our halogenated range. The chlorobutanes and bromopropanes carry one halogen each and are used for single substitutions or Grignard formation; the dichloride is used where a four-carbon bridge has to be built between two nucleophiles, as in adiponitrile synthesis.
Handling 1,4-Dichlorobutane on Your Site
Written for the person who receives the drum, not for a brochure.
- Verify the GC assay before a chain extension step, since monofunctional impurities cap the product
- Check the Karl Fischer figure if the second substitution is moisture sensitive
- Keep drums sealed in store
- Ship and handle as dangerous goods
1,4-Dichlorobutane FAQ
What assay does it carry?
99.59% minimum by GC, with moisture at 0.059% maximum by Karl Fischer.
What is it used to make?
Mainly as raw material and solvent for organic synthesis, used in the synthesis of adiponitrile and carboxymethyl drug routes.
What does it look like?
A clear colourless liquid.
How is it packed?
180 kg per drum, tank truck for bulk, and packing to user requirements.
Why choose a dichloride over two separate steps?
The 1,4-difunctionality gives a four-carbon spacer in a single reagent, which is why it appears in adiponitrile and carboxymethyl routes.
Is SDS available?
Yes. Ask for the current SDS and COA before the order is confirmed.
