2-Chlorobutane
2-Chlorobutane is the secondary butyl chloride used as an organic synthesis intermediate and solvent, applied in medicines, plasticizers, pesticides, rubber, resins and surfactants. It boils at 69.2 °C at 760 mmHg with a density of 0.87 g/cm³ and a refractive index of 1.393.
What You Get With This Grade

- Physical constants published — density 0.87 g/cm³, melting point -140 °C, refractive index 1.393
- Named end uses across six industries rather than a generic solvent description
- 180 kg drums or tank truck, packed to user requirement
Technical features
- Boiling point 69.2 °C at 760 mmHg
- Melting point -140 °C
- Density 0.87 g/cm³
- Refractive index 1.393
Where 2-Chlorobutane Is Used
Pharmaceutical synthesis
Used in medicines as a synthesis intermediate and solvent.
Plasticizer and resin routes
Applied in plasticizer and resin manufacture.
Pesticide manufacture
Used as an intermediate in crop protection chemistry.
Rubber and surfactants
Serves rubber and surfactant production as intermediate and solvent.
Buyers This Grade Is Built For
- Fine chemical manufacturers needing a secondary butyl chloride
- Surfactant producers using it as an intermediate
- Rubber and resin chemists requiring a low boiling chlorinated solvent
- Pesticide manufacturers who need documented CAS material
What It Stops Going Wrong
- The wrong butyl chloride isomer gives the wrong substitution product
- High boiling solvents cost energy to remove; 69.2 °C keeps that cost down
- Suppliers who cannot state the refractive index leave identity checking to the buyer
- Chlorinated intermediates need DG handling from the first shipment, not the fifth

What We Can Change
Drum or tank truck packing according to user requirements.
Against the Alternatives
2-Chlorobutane boils 9 °C lower than 1-chlorobutane and has a lower melting point at -140 °C against -123 °C. As a secondary chloride it behaves differently in substitution chemistry. Its documented application list is broader, covering medicines, plasticizers, pesticides, rubber, resins and surfactants.
Handling 2-Chlorobutane on Your Site
Written for the person who receives the drum, not for a brochure.
- Order by CAS 78-86-4 to keep the isomer unambiguous
- Check refractive index 1.393 on arrival as an identity test
- Size the condenser for a 69.2 °C boiling point during recovery
- Handle and ship as dangerous goods
