Product Overview

Ethyl propionate is a colorless liquid with a characteristic fruity odor, widely recognized for its versatility as a solvent in laboratory applications. This ester compound, derived from ethanol and propionic acid, boasts a high degree of purity, making it suitable for precise chemical reactions and analytical procedures. Its low viscosity and moderate boiling point of approximately 99°C contribute to its effectiveness in extraction processes, particularly in organic synthesis where controlled evaporation is critical. The compound’s molecular structure (C5H10O2) ensures compatibility with a broad range of organic and inorganic substances, while its relatively low toxicity profile enhances its appeal for routine laboratory use. Ethyl propionate’s stability under standard storage conditions—when kept in tightly sealed containers away from direct sunlight and moisture—further solidifies its position as a reliable reagent. Its refractive index of 1.384 and density of 0.891 g/cm³ at 20°C provide consistent performance metrics for experimental reproducibility. The solvent’s ability to dissolve both polar and nonpolar compounds makes it particularly valuable in chromatographic techniques, where selective solubility is paramount for accurate separation and analysis.

FAQs

1. What is the typical shelf life of Ethyl propionate when stored properly?

When stored in a cool, dry place with the container tightly sealed, Ethyl propionate maintains its stability for up to 24 months from the date of manufacture. Exposure to air or moisture can accelerate degradation, so ensure minimal headspace in the container.

2. Can Ethyl propionate be used as a substitute for ethyl acetate in reactions?

While both are esters, Ethyl propionate has a slightly higher boiling point and different solubility properties compared to ethyl acetate. Substitution depends on the specific reaction requirements, particularly regarding polarity and evaporation rate. Always verify compatibility with your protocol.

3. What safety precautions should be taken when handling this solvent?

Use in a well-ventilated area or under a fume hood, as vapors may cause irritation. Wear nitrile gloves and safety goggles to prevent skin or eye contact. Avoid inhalation and keep away from ignition sources, as it is flammable with a flash point of 12°C.

4. How does the purity of this Ethyl propionate compare to analytical-grade versions?

This laboratory-grade Ethyl propionate is purified to remove most impurities, typically exceeding 98% purity. Analytical-grade versions may undergo additional refinement for trace impurity removal, but this grade is sufficient for general synthesis and most chromatographic applications.
