Product Overview
Denatured Alcohol 200 Proof 3A is a high-purity ethanol solution formulated for industrial and analytical applications. This Technical Grade solvent provides excellent solvency, low water content, and favorable physical properties that support reliable performance in manufacturing processes. The assay typically targets 99.7 wt% ethanol with minimal water (<0.02 wt% typical), enabling precise formulation and consistent results in HPLC mobile phases, extractions, and critical cleaning applications. The material is supplied as a clear, colorless liquid with a characteristic alcoholic odor.
This 200 Proof ethanol is commonly used as a solvent in analytical, laboratory, and industrial settings due to its miscibility with water and most organic solvents. Its low aldehyde content supports reliable quality control in sensitive workflows. This product is suitable for use under inert atmosphere where applicable to minimize oxidation. It aligns with established industry practices for denatured ethanol products used in solvent-based formulations, coatings, and surface preparation.
