Dibutyl sulfate

Dibutyl sulfate (CAS 625-22-9), also referred to as di-n-butyl sulfate or DBS, is a sulfate ester used as a solvent and plasticizing agent in industrial chemical processing.

Where is Dibutyl sulfate used?

• Polymer and lubricant manufacturing: alkylating agent and process chemical
• Plastics and polymer processing: plasticizer improving flexibility and workability
• Lubricant formulation: process solvent
• Specialty chemical synthesis: alkylating reagent introducing butyl groups
• Metalworking fluids: functional additive
• It also serves as a chemical intermediate where sulfate ester chemistry is specified.

Commercial specifications

• Liquid at standard commercial purity levels
• Purity confirmed by certificate of analysis per batch
• Packaging from drums to IBC containers by order volume
