Denatured Alcohol 190 Proof 3C

Product Overview

Denatured Alcohol 190 Proof 3C is a high-purity Ethyl Alcohol solution formulated for rigorous industrial and laboratory use. This denatured ethanol contains carefully controlled denaturants to render the product unsuitable for human consumption while preserving exceptional solvency and a low boiling point. The assay range (min 95%, max 98%; typical 96.8%) reflects stringent quality control by standardized titration with NaOH, ensuring consistent solvent performance across analytical and manufacturing workflows. Typical color (APHA/Hazen) is 10, with an upper specification of 15, indicating low color generation during handling and storage. The product is designed for applications requiring reliable volatility and minimal residue, supported by a wide acceptable water content (max 0.5%; typical 0.2%) as determined by Karl Fischer titration.

Commonly employed as a versatile solvent in HPLC mobile phases, extraction processes, cleaning and degreasing operations, fuel formulation components, and as a laboratory reagent, this 190 proof ethanol is optimized for purity and consistency. In addition to its solvency, the material provides a predictable vapor pressure (59 mmHg at 20°C) and a refractive index of 1.361 at 20°C, supporting precise analytical measurements. The product meets ACS Reagent Grade specifications and USP-NF Monograph requirements, underscoring its suitability for demanding research and industrial applications. Ethyl Alcohol and Ethanol are supplied with appropriate hazard controls and storage guidance to maintain integrity during shelf life of up to 24 months when stored properly.

Safety Precautions

Store in a cool, well-ventilated area away from heat sources and open flames. Use containers made of HDPE or glass to prevent chemical interactions, and keep away from strong oxidizers and acids. Ensure proper personal protective equipment (PPE) including chemical-resistant gloves and safety goggles is worn during handling. Avoid exposure to direct sunlight to prevent degradation of denaturants, and maintain ventilation to control vapors in accordance with applicable regulations.

In case of exposure, follow standard SDS guidance: H225 highly flammable liquid and vapor; H301 toxic if swallowed; H311 toxic in contact with skin; H331 toxic if inhaled; H370 causes damage to organs. For spills or accidental release, evacuate personnel, ventilate area, contain with non-flammable absorbent materials, and dispose of in accordance with local, state, and federal regulations. In the event of ingestion or inhalation, seek immediate medical attention and provide the SDS to responding healthcare professionals.

Benefits

✔ High Purity and Consistent Quality – ACS Reagent Grade and USP-NF monograph compliance ensure reliable solvent performance across analytical and manufacturing processes.
✔ Low Impurity Profile – Controlled aldehydes, trace metals, and water content minimize interference in sensitive analyses and extractions.
