CAS: 105-66-8 (n-Propyl n-butyrate)
Boiling point: 142–143°C (atmospheric pressure)
Melting point: Approx. -95°C
Density: 0.873–0.877 g/cm³ (20°C)
Refractive index: n²⁰ᴅ ≈ 1.400
Solubility: Solubility in water is approx. 0.1 g/100 mL (20°C; practically insoluble); miscible with ethanol, diethyl ether, acetone, ethyl acetate, hydrocarbons, and most resins; good solvent for nitrocellulose and acrylic resins
Flash point: 33–34°C (closed cup); flammable liquid (GHS Category 3)
Vapor pressure: Approx. 0.6 kPa at 20°C; moderately slow evaporation rate
Explosion limits: Approx. 1.0%–6.0% v/v

Flavoring agent (food/personal care): FEMA 2933, GRAS; pineapple, apricot, banana, and creamy notes; used in trace amounts in baked goods, confectionery, and beverages.
Solvent: For medium-to-high boiling point coatings, inks, and adhesives; offers better leveling properties than ethyl butyrate and a sweeter odor than amyl acetate.
Organic synthesis intermediate: For producing butyrate-based pharmaceuticals, pesticide side chains, and specialty esters.
Extractant: For the separation of fragrance essential oils.

Toxicity: Low toxicity. Oral LD₅₀ (rat) ≈ 3.2 g/kg; high vapor concentrations cause mild anesthesia/dizziness; liquid causes mild eye irritation; minimal percutaneous absorption.
GHS: H226 Flammable liquid and vapor; H319 Causes serious eye irritation.
Storage and Transport: Class 3, PG III; store in a cool, well-ventilated area (≤30°C), kept separate from oxidizing agents and strong bases.
