Amyl Acetate ACS Grade

Product Overview

Amyl Acetate ACS Grade is a clear, colorless liquid (CAS 123-92-2) formed by the esterification of acetic acid with amyl alcohol. This ACS-grade pentyl ethanoate is characterized by a fruity, banana-like odor and is selected for precise analytical and industrial solvent applications due to its favorable volatility, moderate flash point, and compatibility with a wide range of substrates. With a typical assay of 99.6 wt% and stringent impurity control, it delivers consistent performance in both laboratory and manufacturing environments. The product exhibits a logarithmic balance of solvency and evaporation rate, enabling reliable chromatographic separations and coatings formulations while maintaining low acidity to minimize interference in sensitive methods. Its refractive index and density at standard conditions provide rapid QC verification, supporting robust batch-to-batch consistency in quality systems aligned with ACS Reagent Grade and USP-NF Monograph standards.

Its ACS Grade status and strict impurity thresholds are designed to meet rigorous industry requirements for solvents used in analytical chemistry, pharmaceuticals, and fragrance manufacturing. The material is typically stored under inert conditions to prevent oxidation and degradation, and is compatible with HDPE or glass containment. With a boiling range of 150–154°C and a vapor pressure of approximately 5.5 mmHg at 20°C, Amyl Acetate offers predictable evaporation characteristics suitable for controlled solvent delivery in precision processes and formulation workflows.

Safety Precautions

Handling and storage should follow standard chemical hygiene practices. Store in a cool, dry place away from heat and open flames in compatible containers (HDPE or glass). Ensure adequate ventilation to control vapor buildup and minimize inhalation exposure. Wear appropriate PPE, including chemical-resistant gloves and splash goggles, when handling. Use grounded equipment and avoid contact with strong oxidizers and acids to maintain product integrity and reduce hazard risk.

In case of exposure, consult the SDS for detailed emergency procedures. The substance is designated as highly flammable (H225), may cause eye irritation (H319), and can cause drowsiness or dizziness (H336). Inhalation or contact with eyes and skin warrants immediate attention: eyes should be rinsed cautiously with water for several minutes; skin should be washed with soap and water; if inhaled, move to fresh air and seek medical advice if symptoms persist; if ingested, rinse mouth and seek medical attention.
