Appearance: Colorless to pale yellow transparent liquid (may turn slightly yellow upon prolonged storage or exposure to light due to autoxidation)
Boiling point: 133–135°C (atmospheric pressure)
Melting point: Approx. -20°C
Density: 0.878 g/cm³ (20°C), 0.872 g/cm³ (25°C)
Refractive index: n²⁰ᴅ ≈ 1.462
Solubility: Sparingly soluble in water; miscible with ethanol, diethyl ether, acetone, ethyl acetate, and hydrocarbons
Flash point: 33°C (closed cup); flammable liquid (GHS Category 3)
Vapor pressure: Approx. 7 mmHg (0.93 kPa) at 20°C; moderately volatile
pKa/Acidity/Basicity: Neutral molecule, though the α,β-unsaturated aldehyde moiety is electrophilic

Flavoring Agents/Food Flavors: FEMA 3646, JECFA-approved; available in cherry, raspberry, blackcurrant, nut, bread, and chicken flavor profiles; usage levels in the mg/kg range.
Synthetic Intermediates: For the production of citral, isophytol (Vitamin E side chain), Vitamin A, carotenoids, and pharmaceutical/agrochemical intermediates.
Organic Reaction Reagents: Model compounds for α,β-unsaturated aldehydes; used in hydrogenation (Ru/Pt/Rh) and electrochemical dimerization studies.

Toxicity: Low to moderate toxicity. Oral LD₅₀ (rat) ≈ 690 mg/kg; dermal LD₅₀ (rabbit) ≈ 3400 mg/kg; inhalation LC₅₀ (rat, 4h) ≈ 3700 mg/m³.
Irritation: More irritating than ordinary saturated aldehydes-poses a risk of severe eye damage (H314/H317: corrosive and sensitizing); inhalation irritates the respiratory tract; high concentrations cause anesthesia.
GHS: Danger; H226 Flammable; H302 Harmful if swallowed; H314 Causes severe skin burns; H317 May cause an allergic skin reaction; H331 Toxic if inhaled.
Storage and Transport: UN 1989, Class 3, PG III; store under nitrogen blanket, sealed, at 2–8°C, protected from light; keep isolated from oxidizing agents, strong acids/bases, and air.
