1. Basic Information
Name: Cinnamaldehyde
Alias: 3-Phenylprop-2-enal
CAS No.: 104-55-2
Molecular Formula: C9H8O1
Molecular Weight: 132.16
2. Physical and Chemical Properties
Physical Properties
- Appearance: Pale yellow to amber transparent oily liquid
- Odor: Strong characteristic cinnamon spicy aroma
- Solubility: Insoluble in water; miscible with ethanol, methanol, propylene glycol, ether, vegetable oils; slightly soluble in glycerin
- Boiling Point: 253 °C (760 mmHg)
- Density: 1.048–1.052 g/cm3 (20 °C)
- Refractive Index: 1.619–1.623 (20 °C)
- Hygroscopicity: Non-hygroscopic
Chemical Properties
- Molecular Structure: Aromatic α,β-unsaturated aldehyde, contains benzene ring, conjugated carbon-carbon double bond and aldehyde functional group
- Aldehyde reactivity: Undergoes oxidation, reduction, condensation, addition reactions; easy to oxidize into cinnamic acid when exposed to air
- Antibacterial activity: Inhibits mold, bacteria and fungi, natural food antiseptic component
- Thermal stability: Stable at room temperature; discoloration and polymerization occur under long-term high temperature
- Photostability: Highly sensitive to UV light; long-term illumination deepens color and generates polymer impurities
- Compatibility: Compatible with most flavor essences and oil-soluble cosmetic raw materials; incompatible with strong oxidants, strong alkalis, ammonia and heavy metal salts

Safety Warning
Mild irritant liquid. Vapor irritates eyes, respiratory tract and skin; long-term contact causes skin allergy. All operations must be carried out in ventilated fume hood with chemical-resistant gloves and safety goggles. Keep away from open flames and heat sources due to flammability. Avoid long-term air exposure to prevent oxidative deterioration. Waste liquid belongs to organic flammable hazardous waste and requires professional centralized disposal.
