What is the synthesis method of 1- (4-iodophenyl) methylamine hydrochloride (1:1)?
To prepare 1 - (4 - chlorobenzyl) ethyl acetoacetate (1:1), the method is as follows:
First take an appropriate amount of ethyl acetoacetate, place it in the reaction kettle, and cool it at low temperature. Take another 4 - chlorobenzyl chloride, slowly add it dropwise to ethyl acetoacetate, and add an appropriate amount of basic catalyst, such as sodium ethanol, to promote the reaction. The dropwise addition process needs to be slow and uniform, and at the same time continue to stir, so that the two are fully mixed, and the reaction can be smooth.
During the reaction, temperature control is extremely important. At the beginning, it is appropriate to maintain a low temperature environment, between 0 ° C and 5 ° C, which can make the reaction start smoothly and avoid the growth of side reactions. After the 4-chlorobenzyl chloride is added dropwise, gradually raise the temperature to near room temperature, about 20 ° C to 25 ° C, so that the reaction continues. At this stage, the reaction process needs to be closely observed, and the degree of reaction can be monitored by thin-layer chromatography or other suitable analytical means.
When the reaction reaches the desired level, use an appropriate amount of acidic solution, such as dilute hydrochloric acid, carefully neutralize the alkaline substances in the reaction system, so that the solution is neutral or slightly acidic. After that, use a method of liquid separation to separate the organic phase. The organic phase is washed several times with an appropriate amount of distilled water to remove impurities.
After the washing is completed, add an appropriate amount of desiccant, such as anhydrous sodium sulfate, to the organic phase to remove residual moisture. Subsequently, the organic solvent is removed by reduced pressure distillation, and the fraction within a specific boiling point range is collected, which is the product of 1- (4-chlorobenzyl) ethyl acetoacetate (1:1).
Throughout the synthesis process, the ratio of raw materials, reaction temperature, catalyst dosage and post-processing steps are all crucial, and fine control is required to obtain a high-purity target product.
What is the market price of 1- (4-iodophenyl) methylamine hydrochloride (1:1)?
What is the market price of 1 - (4 - Chuanxiong) acetylsalicylic acid (1:1)? This is a question about the price of medicine. Today imitate the ancient classical Chinese genre of "Tiangong Kaiwu" to answer it.
Looking at the medicinal material market, the prices of various drugs vary from time to time, with changes in supply and demand, differences in origin, and differences in quality. 1 - (4 - Chuanxiong) acetylsalicylic acid (1:1), its price is also affected by various factors.
Different origins have different prices. If the product is fertile soil and the heaven and earth are beautiful, and its quality is high, the price may be high. On the contrary, the origin is not good, the quality is slightly inferior, and the price is slightly lower. And the amount of output also affects the price. When the production is abundant, the supply exceeds the demand, and the price may decline; when the production is thin, the demand exceeds the supply, and the price tends to rise.
Furthermore, the market demand is also the key. If the current disease depends more on this medicine, doctors use it more, and patients demand more, the price will rise; if there are other medicines to replace, the demand is not prosperous, and the price may be stable and decline.
In addition, the method of processing and the state of preservation are also related to the price. The processing is excellent, the preservation is appropriate, the efficacy is not damaged, and the price is not low; if the processing is crude, the preservation is improper, the efficacy of the medicine is attenuated, and the price is difficult to increase.
However, if you want to know the price of the market, you need to go to the pharmaceutical industry in person, consult the pharmaceutical merchants, or observe the platform for the trading of medicinal materials in order to obtain real-time accurate numbers, which cannot be generalized.
