4-Ethoxybenzaldehyde, with the CAS number 10031-82-0, is an organic compound with significant industrial and laboratory applications. It has a molecular formula of C9H10O2 and a molecular weight of approximately 150.17 g/mol. This product is highly regarded for its high quality and low price, making it an attractive option for various users.
It typically appears as a colorless to pale yellow liquid under normal conditions. The boiling point of 4-Ethoxybenzaldehyde is around 248 - 250 °C, and its melting point is approximately -13 °C. It has a certain solubility in common organic solvents such as ethanol and ether but is sparingly soluble in water.
4-Ethoxybenzaldehyde finds wide applications in different fields. In the field of organic synthesis, it serves as an important intermediate. It can be used in the synthesis of various pharmaceuticals, such as certain anti - inflammatory and analgesic drugs. The aldehyde group in its structure allows it to participate in a series of chemical reactions, including condensation reactions, reduction reactions, etc., which are crucial steps in the synthesis of complex drug molecules.
In the fragrance industry, it is used as a flavoring agent due to its pleasant, sweet - like odor. It can be added to perfumes, colognes, and other scented products to enhance their aroma profiles. Moreover, in the field of agrochemicals, it can be used as a raw material for the synthesis of some pesticides, playing a role in protecting crops from pests and diseases.
When using 4 - Ethoxybenzaldehyde in a laboratory setting, proper safety precautions should be taken. Always wear appropriate protective equipment, such as gloves, goggles, and a lab coat. Since it is flammable, it should be stored and used in a well - ventilated area away from open flames and heat sources.
In organic synthesis, the amount of 4 - Ethoxybenzaldehyde used depends on the specific reaction and the desired yield. It is usually added slowly to the reaction mixture under controlled conditions, such as temperature and stirring speed. After the reaction is complete, appropriate separation and purification methods, such as distillation or chromatography, should be used to obtain the pure product.
In the fragrance industry, it can be directly added to the fragrance formulation in a certain proportion. However, the addition amount needs to be carefully controlled to ensure the stability and quality of the final fragrance product.
Pharmaceutical Synthesis Case: A pharmaceutical research company was working on the synthesis of a new anti - inflammatory drug. They used 4 - Ethoxybenzaldehyde as an intermediate in a multi - step synthesis process. In the first step, they reacted 4 - Ethoxybenzaldehyde with a specific amine compound under mild basic conditions. By carefully controlling the reaction temperature at 50 °C and the reaction time for 3 hours, they achieved a high yield of the intermediate product. After a series of subsequent reactions and purification steps, they successfully synthesized the target anti - inflammatory drug, which showed excellent anti - inflammatory effects in pre - clinical trials.
Fragrance Industry Case: A perfume manufacturing company wanted to create a new perfume with a unique sweet and floral aroma. They added 4 - Ethoxybenzaldehyde to their base perfume formula at a concentration of 5%. Through a series of sensory evaluations and adjustments, they found that this addition significantly enhanced the overall aroma of the perfume, making it more attractive to consumers. The new perfume became a best - seller in the market after its launch.
