To prepare 2,3,3-trimethylindolenine (2% 2C3% 2C3-Trimethylindolenine), p-dimethylaminobenzaldehyde and pinacone are often used as starting materials. In a suitable reaction vessel, mix the two in a certain proportion and add an appropriate amount of catalyst, such as p-toluenesulfonic acid. Heat to a certain temperature to make it condensate, and pay close attention to the change of temperature and the reaction process. After the reaction is completed, the relatively pure 2,3,3-trimethylindolenine can be obtained through separation and purification steps, such as extraction, distillation, and recrystallization.
As for the synthesis of 2-Amino-5-bromopyridine (2-Amino-5-bromopyridine), the common route is to use 5-bromopyridine-2-carboxylic acid as raw material. It is first reacted with appropriate reagents to convert the carboxyl group into a group that is easy to leave, such as an acid chloride. Then the acid chloride is reacted with ammonia or amine reagents to achieve the introduction of the amino group. After the reaction is completed, the pure 2-Amino-5-bromopyridine can be obtained by separation and purification. There are also other synthesis methods, such as using pyridine as the starting material and preparing it through multi-step reactions such as halogenation, nitrification, and reduction. However, this process is more complicated, and the conditions of each step also need to be carefully regulated.

2% 2C3% 2C3-trimethylindolenine (2% 2C3% 2C3-Trimethylindolenine) and 2-amino-5-bromopyridine (2-Amino-5-bromopyridine) are both organic compounds, and their physical and chemical properties have their own characteristics.
2% 2C3% 2C3-trimethylindoline, mostly liquid at room temperature, with a specific odor. Its melting point and boiling point are affected by molecular structure. Due to factors such as intermolecular forces, the boiling point is within a certain range. This compound is insoluble in water, but easily soluble in common organic solvents such as ethanol, ether, etc. This is due to the hydrophobicity of its molecules and the similar interaction between organic solvent molecules. It may undergo reactions such as electron rearrangement due to the presence of indole ring in the molecular structure under light or heating conditions, showing unique chemical activity.
2-Amino-5-bromopyridine is usually white to pale yellow crystalline powder in appearance. The melting point is relatively high, which is related to intermolecular hydrogen bonds and van der Waals forces. It has a certain solubility in water, because amino groups can form hydrogen bonds with water molecules; it has good solubility in organic solvents such as chloroform and acetone. Its chemical properties are active, amino groups are basic and can react with acids to form salts; bromine atoms make pyridine rings more prone to nucleophilic substitution reactions, which are widely used in the field of organic synthesis. < Br >
Both are important raw materials in the research and synthesis of organic chemistry, and play a key role in many fields such as medicine and materials. Chemists can skillfully design synthesis routes based on their physical and chemical properties to prepare a variety of compounds with specific functions.

The prices of 2% 2C3% 2C3 - Trimethylindolenine (2,3,3 - trimethylindoline) and 2 - Amino - 5 - bromopyridine (2 - amino - 5 - bromopyridine) in the market are difficult to determine. The price often varies due to various reasons, such as the supply and demand of the market, the cost of production, the purity of goods, and even the different times and places.
Looking at the legacy of "Tiangong Kaiwu", although these two things have not been involved in the past, it is inferred from the ancient theory of things that the supply and demand situation is very important. If there are many applicants and there are few suppliers, the price will increase; if the supply exceeds the demand, the price may be suppressed. < Br >
The cost of the system is also related to the level of the price. The availability of raw materials, the simplicity of the workmanship, and the difficulty of the technique all contribute to the cost. If the raw materials are rare and the workmanship is complicated, the price will be high.
The pure variety of goods also depends on the variable of the price. Pure ones are effective when used, and the price will be high; miscellaneous ones are inefficient when used, and the price will be low.
In addition, the price is different between time and place. At that time and place, the price may be far from the here and now.
Therefore, in order to know the exact price of these two things in the market, it is necessary to consult the chemical industry, the city's brokers, and carefully observe the current market conditions in order to obtain a more accurate price.

2% 2C3% 2C3-trimethylindoline and 2-amino-5-bromopyridine are both important raw materials for fine chemicals and are widely used in many fields. However, due to their chemical properties, specific regulations must be followed when storing.
2% 2C3% 2C3-trimethylindoline, which is liquid at room temperature and has a certain degree of volatility. It is very sensitive to air and moisture, and it is easy to deteriorate when encountered. Therefore, when storing, it is necessary to ensure that the storage container is well sealed to prevent air and moisture from invading. It should be stored in a cool, dry and well-ventilated place, away from fire and heat sources, to avoid increased volatilization or safety risks. And because of its certain chemical activity, it should not be co-stored with strong oxidants, strong acids, strong bases, etc., to avoid chemical reactions and damage to quality.
As for 2-amino-5-bromopyridine, it is mostly solid under normal conditions. Although the stability is slightly better, it should not be taken lightly. It also needs to be placed in a dry environment to prevent moisture. Because it contains amino and bromine atoms, its chemical properties are active, and it should be stored to avoid contact with substances that can react with it. Such as strong oxidizing agents or reducing agents, they may react with it, causing changes in its structure and properties. At the same time, it should also be noted that the storage temperature should not be too high, and it should be stored in a cool place to prevent adverse changes such as decomposition due to excessive temperature.
To sum up, the key to the storage of these two is to seal, dry, cool, and avoid contact with incompatible objects, so as to ensure their quality for subsequent use.
