Ethanol (Ethyl Alcohol)

Ethanol has applications in industry, pharma manufacturing, research and academia as a reagent as well as a solvent. Because of its relatively low toxicity compared with other alcohols and ability to dissolve non-polar substances, ethanol can be used as a solvent in medical drugs, perfumes, and vegetable essences such as vanilla. In organic synthesis, ethanol serves as versatile intermediate.

Reagent Alcohol (Tax-Free)

Reagent Alcohol (RGA) is a widely used denatured ethanol. Since it is denatured (5 parts by gallon of IPA to 95 parts SDA 3A), it is also not subject to Federal Tax in the U.S.. However a letter of registration or "Letterhead Approval" from the TTB must be on file for quantities greater than 4L and provided to Sigma-Aldrich prior to purchase.

Ethanol (Tax-Paid)

Purchasing 190- and 200-proof ethanol has never been easy, until now! Because these ethanols are federally regulated, a TTB permit is required to purchase 190- and 200-proof ethanol. Sigma-Aldrich takes the hassle out of this process for you. No TTB paperwork is needed, nor any records for you to keep. Sigma-Aldrich immediately pays the federal excise tax (200-proof pure alcohol=$27.00/gallon).

We offer tax-paid ethanol in a variety of grades to meet your application and available in amber glass bottles and Sure/Seal bottles.
