2-AMINO-5-ETHOXYPYRAZINE

2-Amino-5-ethoxylpyrazine is one of the organic compounds. Its properties are off-white to light yellow crystalline powder.
Chemically, this compound contains amino (-NH2O) and ethoxy (-OCH 2O CH). The amino group is basic and can react with acids to form corresponding salts. Because nitrogen atoms have unshared electron pairs, they can participate in many nucleophilic reactions. For example, under suitable conditions, amino groups can be acylated with acyl chloride, acid anhydride, etc. to form amide derivatives.
The presence of ethoxy groups affects the solubility of molecules and the distribution of electron clouds. The ethoxy group acts as the power supply group, which can increase the electron cloud density on the pyrazine ring, thereby affecting the reactivity of the pyrazine ring. From the perspective of solubility, the lipophilicity of ethoxy group makes the compound have a certain solubility in organic solvents such as ethanol and chloroform.

The preparation method of 2-amino-5-ethoxypyrazine is of interest in the field of chemical preparation. There are several ways to prepare it.
First, it can be obtained by the substitution reaction of pyrazine derivatives. With a suitable pyrazine matrix, under specific reaction conditions, ethoxy and amino groups are introduced one by one. First, take the pyrazine compound, add an ethoxy-containing reagent in a suitable solvent, such as an ethoxylation reagent, and under the catalysis of a base, cause the ethoxy group to replace the group at a specific position on the pyrazine ring to form an ethoxy-containing pyrazine intermediate. Then, for this intermediate, an amination reagent, such as ammonia or an amino-containing compound, is used to replace the amino group in another position under suitable reaction conditions to obtain 2-amino-5-ethoxypyrazine. In this process, the choice of solvent is quite critical. Common organic solvents, such as alcohols and ethers, need to be selected according to the characteristics of each step of the reaction to facilitate the reaction. The type and dosage of bases also affect the reaction process. Common bases include sodium hydroxide, potassium carbonate, etc., which need to be precisely regulated.
Second, it can be prepared by constructing pyrazine rings. The suitable raw materials containing nitrogen and oxygen are selected, and the pyrazine ring is constructed through a series of reactions such as condensation and cyclization, and ethoxy and amino groups are introduced during or after cyclization. For example, using ethoxy-containing aldehyde or ketone compounds and nitrogen-containing amine compounds as starting materials, under the catalysis of acid or base, the condensation reaction is first carried out to form an intermediate containing functional groups such as double bonds and amino groups. Then the intermediate undergoes an intramolecular cyclization reaction under heating or specific catalyst to construct the pyrazine ring. After that, if necessary, the required ethoxy and amino groups are precisely introduced through modification reactions to achieve the synthesis of 2-amino-5-ethoxy pyrazine. This path requires fine control of the reaction conditions. Factors such as temperature and reaction time have a significant impact on the purity and yield of the reaction products. Too high or too low temperature may cause more side reactions or incomplete reactions.
When preparing 2-amino-5-ethoxypyrazine, no matter what method is used, attention should be paid to the optimization of reaction conditions and the separation and purification of the product. After the reaction is completed, means such as column chromatography and recrystallization are often used to obtain high-purity target products.

I look at your question, but I am inquiring about the market price of 2-amino-5-ethoxypyrazine. However, the market price of these substances often changes for many reasons, which is difficult to determine.
First, the production of this substance is difficult and easy to distinguish. If the preparation method is complicated, the materials used are scarce, or exquisite skills and equipment are required, the cost will be high, and the price will also rise. On the contrary, if the production method is simple and the raw materials are easily available, the price may be slightly lower.
Second, the state of supply and demand determines the price. If there is a strong demand for this substance in the market and the supply is limited, if it is used in a new and rapidly developing industry, the supply will exceed the demand, and the price will rise. If demand is sluggish and supply is abundant, merchants may reduce prices for sales.
Third, the origin is different, and the price is also different. In different places, due to differences in raw material costs, labor costs, transportation expenses, etc., the price of products varies. For those who are shipped from afar, or due to freight, etc., the price is higher than that produced nearby.
Fourth, the quality affects the price. High-purity, high-quality 2-amino-5-ethoxypyrazine, due to the need for stricter control and more refined processing during preparation, the price must be higher than that of ordinary quality, and it is mostly used in areas with strict purity requirements.
To know the exact market price, you should consult chemical raw material suppliers, traders, or professional chemical product trading platforms and industry reports to obtain current price information.

2-Amino-5-ethoxypyrazine, this is a chemical substance. Its storage conditions are crucial, and it is related to the stability and quality of the substance. According to the ancient principles of "Tiangong Kaiwu", wherever you hide something, you must check its properties and let it be. Only then can it last for a long time.
2-Amino-5-ethoxypyrazine is sensitive to light and heat, so it should be hidden in a cool place, away from direct sunlight. The sun is hot, if you expose this thing, you may cause its chemical changes and damage its quality. Gu Yun: "The sun is strong, and the thing is easy to change, and the cold place can slow it down." This is also called.
Furthermore, the humidity of the air is also the key. The moisture is heavy, which can easily cause substances to get damp, or biochemical reactions. When placed in a dry place, such as with lime and other desiccants, keep it dry, just like the ancients used charcoal to dehumidify and protect materials.
And this substance may have certain toxicity and volatility, and the storage place must be well ventilated. Make the turbid gas easy to disperse, fresh gas can enter, and avoid the accumulation of toxic gas, so as to ensure safety. The ancients also knew the importance of ventilation, and the place where things are stored must be left with ventilation.
Packaging should not be ignored. It should be held in a sealed container to prevent the intrusion of external air, moisture and impurities. Just as the ancients hid treasures in pottery jars and sealed them with wax mud to protect their contents from external disturbances.
In general, the storage of 2-amino-5-ethoxypyrazine needs to be cold, dry, well ventilated and sealed, so that its quality can be guaranteed for later use.
