Precautions

1. It should be stored in a cool, dry and well-ventilated environment, away from direct sunlight and high temperature.

2. This product is flammable to a certain extent and should be kept away from open flames and strong oxidizers (such as peroxides, nitric acid, etc.) to prevent reactions.

3. It is recommended to wear appropriate personal protective equipment such as chemical resistant gloves and goggles when operating.

4. If the liquid contacts the skin, it may cause mild irritation, which should be immediately rinsed with soap and plenty of water. If it contacts the eyes, lift the eyelids and rinse with running water or saline. If severe, seek medical attention immediately.

5. In case of leakage, use absorbent materials (such as sand or activated carbon) for treatment and keep the site ventilated to prevent vapor accumulation.

6. Waste liquid should be handled in accordance with chemical waste standards and should not be discharged directly into the sewer to avoid environmental pollution.

FAQ

1. What's the difference between ethyl cinnamate and methyl cinnamate?

Both are cinnamate esters with similar structures, but ethyl cinnamate has a longer carbon chain, a softer aroma, and a slower evaporation rate. It's often used in high-end fragrances.

2. How can I determine the purity of ethyl cinnamate?

It can be determined by gas chromatography (GC) or infrared spectroscopy (IR). A high-purity sample should be a clear, impurity-free liquid with a pure aroma.
