1% 2C9-pentanediol (NDO) is an organic compound with unique physical and chemical properties and has applications in many fields. In terms of physical properties, 1% 2C9-pentanediol is a colorless and transparent liquid at room temperature, which is convenient for mixing with many substances and is very convenient for solution preparation and other operations. Its odor is weak and does not bring a strong irritating odor, which is very advantageous in applications with strict odor requirements, such as cosmetics, personal care products, etc. 1% 2C9-pentanediol has a high boiling point, which makes it stable at higher temperatures and not easy to evaporate. This not only helps to maintain the stability of the system during the high temperature process, but also reduces the loss caused by volatilization during storage. At the same time, it has a certain water solubility and can be miscible with water in a certain proportion, which lays the foundation for its application in aqueous systems, such as in water-based coatings, water-based inks and other products. When it comes to chemical properties, the 1% 2C9-pentanediol molecule contains two hydroxyl groups, which give it active chemical reaction activity. Hydroxyl groups can participate in esterification reactions and react with acids to form ester compounds. This reaction is of great significance in the synthesis of special structural esters, which are used in plasticizers, fragrances and other fields. At the same time, the hydroxyl group can also undergo dehydration reaction, dehydrating water molecules under appropriate conditions to form olefin compounds, which provides a variety of paths for organic synthesis. In addition, because of its commonality of alcohols, it can be oxidized. Under different oxidation conditions, different products such as aldose and acid can be formed, providing rich possibilities for organic synthesis and being widely used in the field of fine chemical synthesis.

The synthesis method of 1% 2C9-pentanediol (NDO) has been known in ancient times, and it is described by you today. First, cyclopentene is the beginning, and it is obtained by multiple steps. Cyclopentene reacts with peroxy acids to cause epoxidation to form epoxycyclopentane. This epoxy is added to water under suitable acid-base conditions, and the ring is opened to produce 1% 2C9-pentanediol. The reaction is exquisite, such as the "Kaogong Ji" saying "sometimes the sky, the earth has gas, the material has beauty, and the workmanship has ingenuity, and then it can be good". Each step requires timing, gas, material and workmanship. When epoxycyclopentane is opened, the degree of acid and base and the temperature are all key, and a little mistake is wrong. Second, glutaric acid and its esters are used as bases. Glutaric acid or its esters are first reduced to form pentanediol intermediates, and then modified. This reduction method, or using metal hydrides as agents, such as lithium aluminum hydride, is active and can capture the oxygen of carbonyl groups and add hydrogen to form alcohol groups. However, lithium aluminum hydride is strong in contact with water. During operation, it is necessary to avoid water vapor, like walking on thin ice in the abyss. The subsequent modification steps also need to be followed to obtain pure 1% 2C9-pentanediol. Third, the method of biosynthesis is also gradually emerging. Select a specific microorganism and cultivate it in a suitable medium. The microorganism can produce 1% 2C9-pentanediol through its own metabolic pathway and a specific substrate as the source. This way is like a wonderful hand of nature, leveraging the power of microorganisms to turn the ordinary into miraculous. However, the growth of microorganisms is easily influenced by the environment, and the temperature and humidity, pH, and the proportion of nutrients need to be fine-tuned. If you adjust the sound of silk and bamboo, it will be discordant if it is slightly worse. All kinds of synthetic methods have their own advantages and disadvantages. When choosing the method, when reviewing the required quantity, cost, and purity requirements, you can choose it after weighing and choosing it. The purpose of synthesis can be achieved.

1% 2C9 -azelaic acid (NDO) is in the market, what is the fluctuation of its price? The price of azelaic acid in the market often changes for various reasons, and the price of azelaic acid cannot be different. In the past, azelaic acid first appeared in the market, because few people knew about it, and the preparation method was not perfect. Because of its high price, it was not easy for ordinary people to ask for it. At that time, it was only available in a few medicine shops or specific beauty shops, but it was also a rare thing. Later, with the evolution of technology, the preparation method became more and more simple, and the output also increased greatly. In addition, people's awareness of its efficacy is deepening, and demand is gradually rising. At this time, although the price has dropped, in the market, there are still differences depending on factors such as quality, origin, and brand. Generally speaking, those with high quality and from famous manufacturers have high prices; while ordinary products may be slightly cheaper. And the market supply and demand situation is also the main reason for price fluctuations. If demand is strong, even for ordinary products, the price may rise slightly; and when supply exceeds demand, the price may be downward. As for the recent times, the market competition has become more and more intense, and many manufacturers are competing to launch related products of azelaic acid. In order to stand out, various manufacturers may adjust their prices to attract customers. Therefore, the current price of azelaic acid has changed compared with before. Under different sales channels and different packaging specifications, the price difference is quite obvious, but overall, it has gradually become more accessible to the people and more accepted by the public.
