Isopropyl Acetate 99.98% ACS Grade

Product Overview

Isopropyl Acetate 99.98% ACS Grade is a high-purity, colorless ester solvent (also known as 2-propyl acetate) used in critical analytical and industrial applications. It is produced by the esterification of isopropanol and acetic acid, offering high solvency for organic compounds with a characteristic fruity odor. This material meets or exceeds ACS Reagent Grade specifications, ensuring strict limits on water content, acidity, and residue.

Designed for professional environments, this solvent is essential for HPLC mobile phases, pharmaceutical processing, and high-performance coating formulations. Its controlled volatility and specific refractive index support reliable quantitative analysis and reproducible manufacturing results. The product is tested for a narrow impurity profile, including low UV absorbance and minimal metal ions, to prevent baseline drift in chromatography and hydrolysis in solvent blends.

Alliance Chemical supplies Isopropyl Acetate 99.98% in chemical-resistant packaging ranging from 1 Quart lab bottles to 55 Gallon drums, ensuring integrity during storage and transport.

Safety Precautions

Isopropyl Acetate is a Class 3 Flammable Liquid. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Keep containers tightly closed when not in use. Use appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves and safety goggles, to prevent skin and eye contact. Ensure proper grounding and bonding during transfer to prevent static discharge. Refer to the Safety Data Sheet (SDS) for detailed handling and emergency response procedures.
