To prepare 2 - (4 - pyridyl) acetic acid, there are various methods. In the interest of "Tiangong Kaiwu", you can find ancient methods to participate.
First, start with 4 - pyridyl acetonitrile and add acid to hydrolyze it. Take an appropriate amount of 4 - pyridyl acetonitrile, place it in a reactor, slowly inject dilute hydrochloric acid or dilute sulfuric acid, and heat it to a moderate temperature to hydrolyze the cyanyl group of acetonitrile into carboxyl groups. Among them, it is necessary to control the temperature accurately and observe the reaction process to achieve the best effect. After the reaction is completed, the 2 - (4 - pyridyl) acetic acid can be obtained through neutralization, extraction, distillation and other steps.
Second, 4-pyridyl ethanol is used as raw material and oxidized. First prepare 4-pyridyl ethanol, and choose a suitable oxidizing agent, such as potassium permanganate or potassium dichromate. In a suitable solvent, 4-pyridyl ethanol is mixed with an oxidizing agent to adjust the reaction conditions to oxidize the ethanol group to a carboxyl group. After the reaction is completed, the product is obtained by separation and purification methods, such as filtration and crystallization.
Third, 4-pyridyl halogen and diethyl malonate are used as raw materials, and the order of condensation, hydrolysis and decarboxylation is completed. First, the 4-pyridyl halogen is condensed with diethyl malonate under alkali catalysis to form the corresponding condensation product. After hydrolysis with alkali to obtain carboxylate, acidification, and finally decarboxylation by heating, 2- (4-pyridyl) acetic acid can be obtained. This process needs to pay attention to the control of the reaction conditions in each step to preserve the yield and purity.
All these methods have their own advantages and disadvantages. In practice, when the factors such as the availability of raw materials, cost considerations, and high and low yields are carefully selected, a suitable 2 - (4-pyridyl) acetic acid can be prepared.

The storage conditions of 2- (4-thymine) acetic acid are due to the fact that 2- (4-thymine) acetic acid likes a stable environment and avoids strong light, hot topics and humid places, so as to maintain its properties for a long time.
It is also recommended to choose a cool, dry and well-ventilated place. Under strong light, this acetic acid is prone to photochemical changes, causing its structure to change and its properties to be different from the beginning. In the hot topic environment, the molecules are too active, or there is a risk of decomposition. And humid gas can cause it to absorb moisture, and in some situations, it may start the path of hydrolysis, which will damage its quality.
In addition, when this acetic acid coexists with other substances, attention must be paid. Do not co-store with strong oxidants, strong bases, etc. Strong oxidants are strong, and when encountering 2- (4-thymine) acetic acid, it may cause severe reactions, causing danger. Strong bases can react with the carboxyl group of acetic acid and change its chemical properties.
If you want to store 2- (4-thymine) acetic acid for a long time without losing its quality, you must follow the above conditions and be careful to do it, and you will be perfect.
