The synthesis of 2-amino-5-bromothiazole-4-carboxylic acid ethyl ester is an important topic in the field of organic synthesis. Its synthesis often follows a variety of paths.
One of them can be started from thiazole derivatives containing specific substituents. First, take a suitable thiazole matrix and introduce bromine atoms at a specific position. This step may require the help of brominating reagents, and the bromination method is carefully selected according to the reaction conditions and substrate activity. Such as liquid bromine, N-bromosuccinimide (NBS), etc. can be brominating reagents. After the bromine atom is introduced, the amino group is introduced at another key position. This process involves many reactions such as nucleophilic substitution and reductive amination, and depends on the selected synthesis strategy.
Second, the thiazole ring is constructed as the starting point. First, the thiazole ring structure is formed by cyclization of small molecular compounds containing sulfur, nitrogen and other atoms. At the beginning of the reaction, the proportion of reactants, reaction temperature and time are finely regulated to ensure the smooth progress of the cyclization reaction and obtain a thiazole ring with a specific substituent. Subsequently, for the position where bromine atoms and amino groups need to be introduced into the ring, the bromination and amination reactions are carried out in an orderly manner according to the aforementioned similar method.
Third, the conversion of carboxylic acid derivatives is used. If the starting material is a carboxylic acid containing thiazole structure, it can be converted into ethyl ester form first. This process is usually achieved by esterification of ethanol and carboxylic acid under the action of catalysts (such as concentrated sulfuric acid, p-toluenesulfonic acid, etc.). After the formation of ethyl ester, bromine atoms and amino groups are introduced at specific positions in the thiazole ring in sequence.
No matter what route is selected, the reaction conditions of each step need to be carefully controlled, such as temperature, reaction time, and concentration of reactants. And after each step of the reaction, high-purity products should be obtained by means of separation and purification such as recrystallization and column chromatography, which will lay the foundation for subsequent reactions. Only in this way can 2-amino-5-bromothiazole-4-carboxylate be effectively synthesized.

2-Amino-5-bromothiazole-4-carboxylic acid ethyl ester, this is an organic compound. Looking at its structure, the thiazole ring is the group, and the amino group, bromine atom and carboxylic acid ethyl ester group are in specific positions. Its physical and chemical properties are worthy of in-depth study.
When it comes to physical properties, under normal circumstances, it is mostly in the state of white to white-like crystalline powder. Due to the intermolecular force, it has a specific aggregate state. The melting point is about 170-175 ° C. Due to the force of chemical bonds between atoms in the molecule, specific energy is required to cause lattice disintegration when heated. As for solubility, in common organic solvents such as dichloromethane, N, N-dimethylformamide, there is a certain solubility. Due to the interaction between solvents and solute molecules, such as hydrogen bonds and van der Waals forces, the solubility in water is very small. Due to the large difference between molecular polarity and water, it is difficult for water molecules to overcome the intermolecular action of solutes to disperse them.
Chemical properties, amino groups are basic and can react with acids to form salts. This is because the amino nitrogen atom has lone pairs of electrons and can accept protons. The carboxylic acid ethyl ester group can undergo hydrolysis reaction under the catalysis of acid or base. In acid catalysis, the proton first protonates the carbonyl oxygen atom in the ester group to enhance the positive electricity of the carbonyl carbon, and water attacks the carbon positive ion to obtain carboxylic acid and ethanol through a series of steps; in alkali catalysis, the hydroxide ion directly attacks the carbonyl carbon, and then generates carboxylate and ethanol. Although the bromine atom is relatively stable, under certain conditions, in case of strong nucleophilic reagents, a nucleophilic substitution reaction can occur, and the bromine atom is replaced by the nucleophilic reagent. Due to the partial positive electricity of the bromine atom attached to the carbon, it attracts the nucleophilic reagent to attack.

2-Amino-5-bromothiazole-4-carboxylic acid ethyl ester is in the market, and its price range is difficult to determine. According to "Tiangong Kaiwu", the price of things in the past often changed due to time, place, and supply and demand. This compound also follows this path in today's market.
Its price may involve multiple ends. First, the price of raw materials is decisive. If the raw materials for making this product are abundant and easy to obtain, the price may be slightly lower; conversely, if the raw materials are rare, the price must rise. Second, the method of preparation is also related. If the method is simple and efficient, and the cost of production is reduced, the market price may be low; if the technology is complicated, time-consuming, labor and resources are consumed, and the price will be high.
Furthermore, the need of the market is also the main reason. If this product is sought by a large number of people in the fields of medicine and chemical industry, and the supply is in short supply, the price will inevitably rise; if there are few people seeking it, the supply will exceed the demand, and the price may drop. And regional differences also have an impact. In places with abundant materials and convenient production, the price may be inferior to remote places with inconvenient supply.
However, at this time I do not have the exact number, so it is difficult to understand its specific price. To know the exact price of this item in the market, it is advisable to consult the price of chemical raw materials merchants, reference trading platforms, or consult people in the industry to obtain a more accurate price range.

2-Amino-5-bromothiazole-4-carboxylic acid ethyl ester, this is a fine chemical substance. Its storage conditions are quite important, which is related to the quality and stability of this substance.
Under normal conditions, it should be stored in a cool, dry and well-ventilated place. A cool environment can avoid high temperature and cause its chemical properties to change. If the temperature is high, or the thermal movement of the molecule is intensified, it may cause the structure to mutate and damage its chemical activity.
Dry conditions are indispensable. Moisture easily makes this substance damp, or causes reactions such as hydrolysis. In the case of hydrolysis, the molecule interacts with water, and the bond breaks to produce new substances, resulting in impure substances and loss of function.
Good ventilation is also the key. It can disperse volatile substances that may accumulate and prevent the formation of flammable and explosive mixed gases. And it can reduce the contact of impurities in the environment with it and keep it pure.
If this substance is sensitive to light, it needs to be stored in a place protected from light. Light or as a catalyst, induces photochemical reactions to change chemical structures and properties.
When storing, it should also be stored separately from oxidants, acids, bases, etc. Because of these substances or react violently with them, safety accidents such as combustion, explosion, etc.
In conclusion, 2-amino-5-bromothiazole-4-carboxylic acid ethyl ester should be stored in a cool, dry, well-ventilated environment, according to its characteristics or need to be protected from light, and stored separately from specific substances to ensure its quality and safety.
