To prepare 7-hydroxy-1,2,3,4-tetrahydroisoquinoline benzoate (1:1), the following ancient method can be used.
First take an appropriate amount of starting materials, such as phenethylamine and carbonyl compounds with suitable substituents, and put them into the reactor in an ingenious ratio. The kettle is also made of a well-made reactor, which can withstand the temperature and pressure of the reaction. In this kettle, add a suitable catalyst, which needs to be able to promote the progress of the reaction, increase the rate and yield of the reaction. The choice of catalyst is related to success or failure, and it should be carefully considered, depending on the reaction mechanism and past experience.
Then adjust the temperature and pressure of the reaction. When the temperature is used, the power of the reaction should be maintained within a certain range. If it is too high, the raw material may decompose, and if it is too low, the reaction will be delayed. The pressure also needs to be precisely regulated to facilitate the reaction to advance in the desired direction. At this time, the various substances in the kettle interact, the chemical bond is broken and reborn, and the required intermediate is gradually formed.
Wait for the intermediate to be prepared, and then go through a delicate conversion step. Or introduce a specific reagent to react with the intermediate. The amount of this reagent and the reaction time need to be carefully controlled. In the meantime, observe the progress of the reaction and monitor it by appropriate means, such as chromatography, to know the degree of the reaction and the amount of impurities.
After several steps of conversion, carefully separate and purify the product. Separation method, or use extraction, distillation, crystallization and other techniques to remove impurities, improve purity, and make the product reach the required standard. Finally, the 7-hydroxyl-1,2,3,4-tetrahydroisoquinoline benzoate (1:1) is obtained. This product may be used in various fields such as medicine and chemical industry, and is used by the world. The whole synthesis process requires the craftsman's heart and caution to achieve this delicate synthesis.

The "7-%E6%BA%B4-1%2C2%2C3%2C4-%E5%9B%9B%E6%B0%A2%E5%BC%82%E5%96%B9%E5%95%89%E7%9B%90%E9%85%B8%E7%9B%90%281%3A1%29" you mentioned is actually a chemical product. However, it is not easy to know its market price.
The market price often changes due to many factors, one of which is the situation of supply and demand. If the demand for this product is strong and the supply is limited, the price will be high; on the contrary, if the supply exceeds the demand, the price will drop automatically. The second is the cost of raw materials. The difficulty of obtaining raw materials and the rise and fall of prices all affect the cost of this product, which in turn affects its selling price. The third is the production process and technology. Advanced technology can reduce costs and improve quality, which also has an impact on prices. The fourth is policies and regulations and market competition. Policy support or restrictions, the intensity of peer competition, are all related to price.
As far as I know, it is difficult to determine the market price of this product without knowing the detailed origin, quality standards, market circulation, etc. If you want to get an accurate price, you should check the chemical market information in detail, consult industry experts, or refer to recent transaction records, so as to get a more accurate price.

7-Mercapto-1,2,3,4-tetrahydroisoquinolinoformamide (1:1) During storage and transportation, all precautions should not be ignored.
The first choice of environment. When storing, it is advisable to find a cool, dry and well-ventilated place, protected from direct sunlight and moisture. Due to the heat and moisture of sunlight, it can induce qualitative changes and damage its quality. During transportation, it is also necessary to pay attention to the changes in temperature and humidity around to ensure a stable environment.
The second is the solidity of the packaging. The packaging used must be solid and reliable to prevent damage and leakage. Because of its specific chemical properties, if the packaging is not good, it will leak or cause pollution, endangering the surrounding people and things. Packaging materials also need to be carefully selected, should be compatible with the substance, no chemical reaction.
Furthermore, be careful with handling. Whether it is moving during storage, or loading and unloading during transportation, it should be handled with care, and it is strictly forbidden to throw or collide. Violent vibration or impact, or damage to the packaging, may also cause internal changes in the substance.
And it is necessary to prevent mixed transportation. This substance cannot be co-stored and transported with oxidizing substances, acids, alkalis, etc. Because of its active chemical properties, contact with other substances, or violent reactions, such as explosion and other risks.
In addition, identification is indispensable. Storage containers and transportation tools should be clearly marked with the name of the substance, characteristics, hazard warnings and other information. So that relevant personnel can see at a glance, follow the correct procedures during operation, and avoid risks.
Storage and transportation of 7-mercapto-1,2,3,4-tetrahydroisoquinolinecarbonamide (1:1) requires a cautious attitude in the environment, packaging, handling, mixed storage and labeling to ensure smooth process and material safety.
