By measuring the melting point, the purity of the compound can be judged. If the purity is high, the melting point range is narrow; if it contains impurities, the melting point will change, or decrease, or the melting range will become wider.
In terms of boiling point, under certain pressure conditions, the boiling point of 2-ethoxy-5-nitropyridine is [X] ° C. The boiling point is of great significance for the separation and purification of compounds. For example, in distillation operations, it can be separated from the mixture according to the difference in boiling points.

The stability of the chemical properties of 2-ethoxy-5-nitropyridine depends on many aspects. This compound is an organic compound containing a pyridine ring with ethoxy and nitro groups on the ring.
In terms of stability, the pyridine ring has a certain stability due to its aromaticity. In the ethoxy group, the oxygen atom is connected to the pyridine ring, and through the conjugation effect, it can affect the distribution of the molecular electron cloud and stabilize the molecule to a certain extent. However, the nitro group is a strong electron-absorbing group, which will reduce the electron cloud density of the pyridine ring and enhance the electrophilic reaction activity of the carbon atoms on the ring. From this perspective, it may weaken the stability of the molecule, because it is more prone to reaction.
In common chemical environments, 2-ethoxy-5-nitropyridine can remain relatively stable for a certain period of time without special reagents or conditions. However, when encountering strong oxidizing agents, reducing agents, strong acids or strong bases, the stability will be challenged. For example, in a strong acid environment, the nitrogen atom of the pyridine ring may protonate, changing the electronic structure and chemical properties of the molecule; strong reducing agents may cause nitro groups to be reduced.
In summary, the stability of 2-ethoxy-5-nitropyridine is not absolute, and it is relatively stable under specific mild conditions. However, it is in an active chemical environment, and the stability is affected due to the characteristics of the functional groups contained or chemical reactions.

The production process of 2-ethoxy-5-nitropyridine is an important task in chemical synthesis. The method has various paths, the common ones are as follows.
The starting material is mostly selected from suitable pyridine derivatives. One method is to take pyridine first, and introduce ethoxy group through a specific substitution reaction. In this step, ethanol and suitable bases are often used as reagents. At an appropriate temperature and reaction time, nucleophilic substitution occurs, and ethoxy is added at a specific position in the pyridine ring.
Then, for the pyridine intermediate that already contains ethoxy groups, a nitration reaction is carried out. During the nitration process, the mixed acid of nitric acid and sulfuric acid is used as the nitrifying agent. The ratio of mixed acid, reaction temperature and time need to be precisely controlled. If the temperature is too high, it may cause excessive nitrification of the pyridine ring or other side reactions; if the temperature is too low, the reaction rate will be slow and the yield will not be high. In this reaction, the nitro group will be selectively introduced into the appropriate position on the pyridine ring to generate 2-ethoxy-5-nitropyridine.
Another way of thinking is to nitrate the pyridine first to obtain the pyridine derivative containing the nitro group, and then perform the ethoxylation reaction. However, this order needs to consider the influence of the nitro group on the subsequent ethoxylation reaction, and the reaction conditions are more stringent.
During the whole synthesis process, factors such as the purity of the raw material, the material and sealing of the reaction equipment, and the stirring rate are all related to the purity and yield of the product. After the reaction, the high purity 2-ethoxy-5-nitropyridine can be obtained by extraction, distillation and recrystallization.

In today's world, it is not easy to know the price range of 2-ethoxy-5-nitropyridine in the market. The price of these chemical substances often varies for a variety of reasons.
The first to bear the brunt is the difficulty of production. If the preparation of this 2-ethoxy-5-nitropyridine is complicated, requires rare raw materials, exquisite processes, and consumes a lot of manpower and material resources, its price will be high. On the contrary, if the preparation method is simple and the raw materials are common and easy to obtain, the price may be slightly lower.
Furthermore, the state of market supply and demand is also the key. If many industries compete for this 2-ethoxy-5-nitropyridine, the demand is like a tide, and the production is limited, the supply is in short supply, and the price will rise. If there is little demand, excess output, and oversupply, the price will tend to drop.
In addition, the different suppliers also make the price different. Big businesspeople, with the benefit of scale and wide channels, may be able to sell it at a lower price. And small shops, due to cost, the price may be high.
Looking at the market conditions of the past, the price of these chemicals fluctuates. According to the common condition, the price of 2-ethoxy-5-nitropyridine per gram may be between tens of yuan and hundreds of yuan. However, this is only a rough estimate, and the actual price should be subject to real-time inquiry and quotations from various suppliers. Market conditions are ever-changing. If you want to get an accurate price, you need to go to the market in person, inquire from many parties, and compare in detail before you can get it.
