ETHOXYCOUMARIN, 7- - Introduction
7-ethoxycoumarin is an organic compound with the chemical formula C11H10O3. It is a white crystalline solid with an aromatic taste.
7-ethoxycumarin is commonly used in fluorescent dyes and biosensors. It can be excited to emit blue light, so it is widely used in fluorescence microscopy, optical sensors and chemical analysis.
There are a variety of methods for preparing 7-ethoxycumarin. One commonly used method is through the condensation reaction of acetoimines. In detail, benzaldehyde and acetoethyl ketone are first reacted to obtain 7-ethanyl coumarin, and then a keto-alcohol equilibrium reaction is carried out with ethanol and potassium hydroxide to obtain the final 7-ethoxycoumarin.
Regarding safety, there are few relevant toxicity data for 7-ethoxycoumarin, but it is generally considered to have low toxicity. However, it is still necessary to follow regular laboratory practices and safety procedures to avoid contact with skin, eyes and inhalation. Attention should be paid to personal protective measures during use, such as wearing gloves, goggles and masks. At the same time, care should be taken during storage and handling to avoid contact with ignition and oxidizing agents.
