In stockPrice varies by Size.
190 proof ethanol, USP, released against a certificate of analysis specifying a minimum of 190 proof and a minimum of 94.9 % ethanol by volume. Proof and specific gravity at 60 °F are determined by ASTM D-4052, acidity by ASTM D-1613, and residual impurities including methanol, acetaldehyde, benzene, esters, propanols and amyl alcohols by GC-FID. Available in 1 quart, 1, 5, 55 and 275 gallon volumes.

Description
Ethanol at 190 proof, meeting USP test requirements. Each lot is released against a certificate of analysis rather than a nominal grade statement, which matters if your method or your quality system requires a documented impurity profile rather than a label claim.
Certificate of analysis scope
The reference certificate specifies a minimum of 190 proof and a minimum of 94.9 % ethanol by volume. The test panel covers:
- Proof and specific gravity at 60 °F – ASTM D-4052
- Percentage ethanol by volume – ASTM D-4052
- Acidity – ASTM D-1613
- Clarity of solution, non-volatile matter, ultraviolet absorbance at 240 nm, 250-260 nm and 270-340 nm, and permanganate time – USP methods
- Colour (Pt-Co) and appearance – visual; odour – organoleptic
- Acetaldehyde, methanol, esters as ethyl acetate, propanols, benzene, amyl alcohols and the sum of all other impurities – GC-FID
Hazard identification
The safety data sheet lists ethanol, CAS 64-17-5, at 75-100 % w/v, classified under 29 CFR 1910.1200 as Flammable liquid category 2 (H225, highly flammable liquid and vapour) and Eye irritation category 2 (H319). Signal word: Danger. Store away from heat, sparks, open flames and other ignition sources, and keep away from combustible materials.
Volumes
Supplied in 1 quart, 1 gallon, 5 gallon, 55 gallon and 275 gallon volumes, plus a four-quart case.
Frequently asked questions
What purity is certified?+
The reference certificate of analysis specifies a minimum of 190 proof and a minimum of 94.9 % ethanol by volume, with proof and specific gravity at 60 °F determined by ASTM D-4052.
Is it denatured?+
No. This is 190 proof ethanol tested to USP requirements; the safety data sheet lists ethanol, CAS 64-17-5, as the only hazardous component at 75-100 % w/v. If you need a denatured product for a tax-exempt industrial application, look at the SDA 3A or CDA 12-A grades instead.
What impurities are tested for?+
Acetaldehyde, methanol, esters as ethyl acetate, propanols, benzene, amyl alcohols and the sum of all other impurities, all by GC-FID. The certificate also covers acidity by ASTM D-1613 and USP clarity, non-volatile matter, ultraviolet absorbance at 240 nm, 250-260 nm and 270-340 nm, and permanganate time.
What are the GHS hazards?+
Flammable liquid category 2 (H225, highly flammable liquid and vapour) and eye irritation category 2 (H319) under OSHA 29 CFR 1910.1200. Signal word Danger. Keep away from heat, hot surfaces, sparks, open flames and other ignition sources, and store away from combustible materials.
What container sizes are available?+
1 quart, a four-quart case, 1 gallon, 5 gallon, 55 gallon drum and 275 gallon tote.
Can a certificate of analysis be supplied for the lot I receive?+
Yes. Request the lot-specific certificate of analysis with your order and we will forward it. The certificate carries the lot number, the analysis date and the results against specification for every test in the panel above.
