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.

It functions as an alkylating agent and process chemical in polymer and lubricant manufacturing, where controlled reactivity and solvency are required for specific industrial applications.

In plastics and polymer processing, DBS acts as a plasticizer to improve flexibility and workability in finished polymer compounds. Lubricant formulators use it as a process solvent.

It also serves as a chemical intermediate where sulfate ester chemistry is specified. It serves as an alkylating reagent in specialty chemical synthesis, enabling the introduction of butyl groups.

This process occurs into target molecules under controlled conditions. Metalworking fluid formulators may incorporate it as a functional additive where ester-based chemistry contributes to performance.

Dibutyl sulfate is supplied as a liquid at standard commercial purity levels suited to industrial and specialty chemical applications. Technical grade is the primary market form available.

Purity specifications are typically confirmed by certificate of analysis for each batch. Packaging ranges from drums to IBC containers depending on the specific order volume required.
