It belongs to the phenylpropene family and is characterized by its conjugated system linking a benzene ring to an aldehyde group through a double bond in E-configuration.

(E)-3-phenylprop-2-enal is a pale yellow to colorless liquid at room temperature with a characteristic sweet, cinnamon-like odor. The compound has a density of approximately 1.05 g/cm³ and a boiling point around 248°C. It is slightly soluble in water but readily dissolves in organic solvents like ethanol, ether, and oils. The compound is sensitive to light and air oxidation.

(E)-3-phenylprop-2-enal is primarily used in the fragrance and flavor industry as a key component in cinnamon flavoring and perfumery. It serves as an intermediate in pharmaceutical synthesis and is employed in the production of various chemicals including α-amylcinnamaldehyde. The compound also finds applications in cosmetics, food additives, and as a starting material for organic synthesis reactions.

(E)-3-phenylprop-2-enal requires careful handling as it is classified as Skin Sens. 1A (skin sensitizer). Operators must wear appropriate personal protective equipment including nitrile gloves, safety goggles, and protective clothing. Ensure adequate ventilation to avoid inhalation exposure. Avoid direct skin and eye contact. Work in well-ventilated areas or under fume hoods when handling larger quantities.

(E)-3-phenylprop-2-enal should be stored in tightly sealed containers in a cool, dry, and dark place away from heat sources and direct sunlight. The storage temperature should be below 25°C to prevent degradation. Keep away from strong oxidizing agents and bases. Use amber glass bottles or other light-protective containers to minimize photodegradation. Ensure proper labeling and maintain inventory rotation.

In case of skin contact with (E)-3-phenylprop-2-enal, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air. Given its skin sensitizing properties, monitor for allergic reactions and consult a physician if symptoms develop.

(E)-3-phenylprop-2-enal waste must be disposed of according to local and national hazardous waste regulations. The compound should not be discharged into drains, sewers, or the environment. Contact licensed waste disposal companies for proper treatment and disposal. Small quantities can often be incinerated at high temperatures in appropriate facilities. Maintain proper documentation of waste disposal activities as required by regulations.

(E)-3-phenylprop-2-enal transport requirements depend on quantity and local regulations. While not specifically classified under ADR dangerous goods regulations, it should be transported in properly labeled, leak-proof containers. Ensure compliance with GHS labeling requirements including the Warning signal word and GHS07 pictogram. Use appropriate packaging materials resistant to the chemical and follow carrier-specific guidelines for chemical shipments.

(E)-3-phenylprop-2-enal is subject to CLP regulation requiring classification as Skin Sens. 1A with appropriate labeling including Warning signal word and GHS07 pictogram. It falls under REACH registration requirements for chemical substances. The compound is not currently listed as a SVHC (Substance of Very High Concern). Food and cosmetic applications may be subject to additional sector-specific regulations regarding purity and usage levels.
