Product Overview
Denatured Alcohol 200 Proof 3C is a high-purity, anhydrous ethanol solution rendered unsuitable for human consumption through the addition of isopropyl alcohol (Formula 3C). This high-purity solvent delivers exceptional solvency and a low boiling point, making it a critical resource for industrial and analytical workflows. With a typical assay of 99.5 wt% ethanol, it ensures consistent performance in solvent-based processes, including botanical extraction, heavy-duty degreasing, and chromatographic applications.
Designed to meet strict industrial specifications for purity, this product features low residue on evaporation and minimal heavy metal contamination. It is compatible with sensitive chemical reactions and precision cleaning requirements. Its clear, colorless appearance and characteristic alcoholic odor differ from methanol-denatured formulations, making Formula 3C the preferred choice for applications where isopropyl alcohol is a more compatible denaturant.
This denatured ethanol supports a broad spectrum of technical applications, from the solvent extraction of active ingredients to use as a mobile phase in HPLC systems. The product's low residue (typical 0.001%) ensures minimal interference in analytical methods. Proper handling, storage, and adherence to SDS guidelines are required for safe operation in facility environments.

Safety Precautions
Denatured Alcohol 200 Proof 3C is a flammable liquid. Handling and storage must follow standard industrial safety practices: keep in a cool, well-ventilated area away from ignition sources, store in HDPE or glass containers, and utilize proper grounding/bonding for large volumes (55-gallon drums and totes) to prevent static discharge. Operators must wear appropriate PPE, including chemical-resistant gloves and splash goggles.
Refer to the Safety Data Sheet (SDS) for comprehensive exposure limits and emergency response procedures. In the event of exposure, rinse affected areas immediately and seek medical attention.
Benefits
High Purity – Anhydrous 200 Proof formulation supports moisture-sensitive processes.
Formula 3C – Denatured with Isopropyl Alcohol, avoiding Methanol for specific compatibility needs.
