Product Overview
Denatured Alcohol 200 Proof 3A is an ethanol-based solvent rendered unfit for beverage use by the addition of a small amount of denaturant. Classified as Technical grade, this product serves buyers who need a high-proof ethanol solvent for industrial processes — extraction, equipment cleaning, formulation work, or fuel blending — without the regulatory overhead of undenatured spirits.
The "3A" designation identifies the specific denaturing formula applied to this ethanol. Because the denaturant makes the product non-potable, it can be purchased and used in industrial settings without the excise-tax burden that applies to beverage alcohol. That distinction matters to procurement teams managing solvent costs at scale.
Alliance Chemical offers this product in pack sizes from 1-quart bottles through 330-gallon totes, covering everything from bench-scale lab work to continuous production runs.
Why This Concentration
At 200 proof, this ethanol is essentially anhydrous — the strongest concentration commercially available. That matters in processes where residual water interferes with performance. Extraction work, for example, is more efficient when the solvent carries minimal moisture. Cleaning and degreasing operations benefit from faster evaporation and fewer residues.
The Technical grade designation tells a buyer this product is intended for industrial solvent applications, not analytical or pharmaceutical work. If your process demands a denatured ethanol solvent and does not require a specific certified purity standard, Technical grade is the practical choice: it delivers the solvency of full-proof ethanol at a lower cost point than specialty grades.
Buyers should verify that the 3A denaturing formula is compatible with their process. In most industrial solvent, cleaning, and fuel-blending applications, 3A denatured ethanol performs without issue. For extraction or formulation work, confirm that trace denaturant residues will not affect the end product.
Chemical Profile
Denatured Alcohol 200 Proof 3A (CAS 64-17-5) has the molecular formula C2H6O and a molecular weight of 46.07. It is a liquid with a pleasant odor and a density of 0.79 at 68 °F — less dense than water and will float on it. The product is fully miscible in water, with solubility greater than or equal to 100 mg/mL at 73 °F. Vapor pressure runs 40 mmHg at 66 °F and 50 mmHg at 77 °F, which accounts for its quick evaporation rate at room temperature. That volatility is an asset in cleaning and extraction, but it also means storage and handling must account for flammable vapor buildup.
Industrial Applications
Denatured Alcohol 200 Proof 3A is a workhorse solvent across multiple industries. Its fast evaporation, strong solvency, and water miscibility make it useful wherever a clean, volatile organic solvent is needed.
-
Solvent for extraction — Used to extract target compounds from plant materials and other matrices. The anhydrous character of 200-proof ethanol improves extraction efficiency by reducing water content in the solvent stream, which can affect selectivity and downstream processing.
-
Industrial cleaning — Effective for removing oils, greases, and residues from equipment, tooling, and glassware. Evaporates cleanly, leaving minimal residue behind — a practical advantage over slower-drying solvents in production environments where turnaround time matters.
-
Cosmetic formulation — Functions as a solvent carrier in personal-care product manufacturing, helping dissolve and distribute ingredients during the formulation process.
-
Fuel blending — Serves as a component in fuel formulations. Its oxygen content and combustion characteristics make it a functional additive in certain fuel blends.
-
HPLC mobile phase — Used as a mobile-phase component in reversed-phase chromatography for separating organic compounds in analytical workflows.
Handling & Storage
This product carries a signal word of Danger (per the product's GHS classification). The three governing hazard statements are:
- H225: Highly flammable liquid and vapour (per the product's GHS classification)
- H319: Causes serious eye irritation (per the product's GHS classification)
- H370: Causes damage to organs — central nervous system, optic nerve (per the product's GHS classification)
Handle with appropriate PPE: chemical-resistant gloves and safety goggles at a minimum. Work in a well-ventilated area or under local exhaust ventilation. The vapor pressure of this product means flammable vapors accumulate quickly in enclosed spaces — eliminate all ignition sources, open flames, and sparks in the work area.
Store in a cool, well-ventilated location away from heat sources, direct sunlight, and incompatible materials. Keep away from strong oxidizers and strong acids. Use containers made of HDPE or glass. Keep containers tightly closed when not in use to limit vapor release and moisture uptake.
Hazmat & Shipping
Denatured Alcohol 200 Proof 3A is a regulated hazardous material for transport. Every shipment from Alliance Chemical is classified, packaged, marked, and documented in accordance with DOT requirements. The governing transport data:
-
UN Number: UN1987 (per 49 CFR 172.101)
-
Hazard Class: 3 — Flammable Liquid (per 49 CFR 172.101)
-
Packing Group: II (per 49 CFR 172.101)
-
Proper Shipping Name: Alcohols, n.o.s. (Ethyl alcohol, methanol) (per 49 CFR 172.101)
As a Class 3, Packing Group II flammable liquid, this product requires full DOT-compliant packaging, hazard labels, and shipping documentation for every shipment. Our warehouse team in Taylor, TX handles hazmat shipments daily — proper classification and paperwork are built into our fulfillment process.
