Diethyl Sulfate CAS 64-67-5

What Diethyl Sulfate Is

Diethyl Sulfate is the diethyl ester of sulfuric acid, with the linear structure (C2H5O)2SO2. The oily liquid is denser than water, soluble in alcohol and ether and slowly broken down by water. The ethyl groups transfer readily to nucleophiles, making the material a standard ethylating reagent. As a toxic liquid under UN 1594 it needs careful handling. UATChem supplies technical material, with assay, acidity and identity on the COA and TDS.

Dye, Pharmaceutical, Agrochemical and Synthesis Uses

• Dyes. It ethylates dye intermediates, introducing the ethyl group into amines and phenols used in colorant production.
• Pharmaceutical. It serves as an ethylating reagent in pharmaceutical routes that need an ethoxy or N ethyl step.
• Agrochemical and fine chemical. It goes into crop protection intermediates and general fine chemical synthesis where a controlled ethyl transfer is wanted.

Typical Specifications

Assay and acidity vary by grade and are reported on the COA and TDS, while toxicity and safe handling are covered by the SDS; the table below identifies the material.

Packaging, Documents and Ordering

• Orders ship in plastic jerrycans or 200 kg steel drums, and bulk volumes in 1000 kg IBC totes, matching the photos. Keep the liquid sealed and cool, away from moisture because of the slow hydrolysis.
• Under UN 1594 the material is handled as a poison (Class 6.1), and every lot comes with a COA, TDS and SDS covering assay, acidity and emergency advice.
• Samples are available for evaluation. To quote, UATChem needs the grade, quantity, packing and destination port.

FAQ

Q: What is diethyl sulfate used for?

A: It is an ethylating reagent for dye intermediates, pharmaceutical and agrochemical routes and fine chemical steps.

Q: How is diethyl sulfate packed?

A: UATChem supplies it as an oily liquid in jerrycans, 200 kg steel drums and 1000 kg IBCs, with other packing on request.

Q: How does diethyl sulfate react?

A: It transfers an ethyl group to amines, phenols and alcohols and hydrolyzes slowly in water, so it is handled as toxic.

Q: What documents come with diethyl sulfate?

A: Every lot ships with a COA, TDS and SDS covering assay, acidity, the UN 1594 poison classification and safe handling.
