It is also indispensable in the food industry. It can be used as a food additive to increase the aroma and flavor of food. In the production of baked goods, beverages, candies, etc., adding an appropriate amount can simulate the natural fruity or floral aroma and lure consumers' appetite. For example, when making citrus-flavored beverages, adding this compound can make the beverages have a realistic fruity aroma, similar to natural citrus juicing, just like "ingenious, and the taste is natural".
Furthermore, in the field of organic synthesis, it is an important intermediate. Using it as a starting material, through various chemical reactions, a variety of organic compounds with special functions can be prepared. According to the principle of "Tiangong Kaiji", "If you want to be good at something, you must first sharpen your tools", this compound provides convenience for organic synthesis and helps chemists produce the fine chemicals required. It is widely used in medicine, pesticides, materials and other industries.

4- (1-methylethyl) -2-nitrobenzoate ethyl ester, this is an organic compound. Its physical and chemical properties are complex, let me talk about them one by one.
Looking at its physical properties, under room temperature, or in a liquid state, it has a specific color and odor, but the specific color and taste vary depending on purity and environment. Its boiling point is related to the intermolecular force. There are van der Waals forces and hydrogen bonds between molecules, resulting in a certain range of boiling points. Generally speaking, groups such as benzene ring and nitro group enhance the intermolecular force and have a relatively high boiling point. Its melting point is also affected by the molecular structure, molecular arrangement regularity and symmetry, which determine the lattice energy, which in turn affects the melting point.
As for the chemical properties, it is active because it contains a variety of functional groups. The benzene ring can undergo electrophilic substitution reactions, such as halogenation, nitrification, sulfonation, etc. The nitro group is a strong electron-absorbing group, which reduces the electron cloud density of the benzene ring and is more prone to electrophilic substitution. The substitution check point is selective, mostly in the meta position. Ester groups can be hydrolyzed. Under acidic or alkaline conditions, acids and alcohols are formed respectively, and alkaline hydrolysis is more complete. The alkyl group can participate in free radical substitution reactions, etc.
The properties of this compound are of great significance in the fields of organic synthesis, medicinal chemistry, etc. Because of its reactivity, it can be used as an intermediate to produce complex organic molecules through a series of reactions, providing a key material basis for drug research and development

The synthesis method of 4- (1-methethyl) -2-nitrobenzoate ethyl ester is a very important topic in the field of organic synthesis. To prepare this substance, the common methods are as follows:
First, use ethyl benzoate as the starting material. Nitration reaction of ethyl benzoate is carried out first. In this process, careful selection of nitrifying reagents and reaction conditions is required. Generally speaking, mixed acids (a mixture of sulfuric acid and nitric acid) can be used as nitrifying reagents. At a suitable temperature and reaction time, the benzene ring of ethyl benzoate can be successfully introduced into the nitro group to generate 2-nitrobenzoate ethyl ester. Subsequently, the upper position of 2-nitroethyl benzoate is alkylated to introduce a (1-methylethyl) group. At this time, a suitable halogenated hydrocarbon, such as 2-halopropane, can be selected to achieve alkylation under the catalytic action of alkali, and finally obtain the target product 4- (1-methylethyl) -2-nitrobenzoate ethyl ester.
Second, another route can also be started. First, the benzene is alkylated to introduce a (1-methylethyl) group to generate isopropylbenzene. Then, the nitration reaction of isopropyl benzene is carried out. Since isopropyl is an ortho-para-site group, the reaction conditions can be precisely adjusted so that the nitro group is mainly introduced into the ortho-site to generate 2-nitro-4-isopropylbenzene. Then, through a series of oxidation reactions, the isopropyl group is converted into carboxyl group to obtain 4- (1-methethyl) -2-nitrobenzoic acid. Finally, the acid is esterified with ethanol, and under the action of concentrated sulfuric acid and other catalysts, ethyl 4- (1-methylethyl) -2-nitrobenzoate is formed.
These two synthesis methods have their own advantages and disadvantages. In actual operation, it is necessary to comprehensively consider the availability of raw materials, the difficulty of controlling reaction conditions, the level of yield, and the impact on the environment, among other factors, in order to choose the most suitable synthesis path.

4- (1-methethyl) -2-nitrobenzoate ethyl ester, this product is in the market price range, and it is difficult to break. The price of this product is determined by many factors, such as the quality of the product, the situation of supply and demand, the difficulty of preparation, and the geographical and timely transaction.
If the quality is high, impurities are rare, and the preparation process is exquisite and complicated, the required raw materials are rare and rare, and the price must be high. On the contrary, if the quality is slightly inferior, the preparation is easy, and the raw materials are common, the price may be low.
Looking at the supply and demand, if the market demand for this product is strong, and the supply is short, the price will rise; if the demand is small, the supply is abundant, and the price may decline.
The time and region of the transaction are also affected. Different regions have different prices due to logistics costs and market conditions. Seasons change, and the supply of raw materials may change, which can also cause price fluctuations.
Overall, the price may fluctuate between tens of yuan per gram and hundreds of yuan per gram. However, this is only a rough guess, and the actual price needs to be determined according to specific market conditions.
