This low temperature melting point makes the compound exist in liquid form at room temperature. The boiling point is relatively high, roughly around 300 ° C. The higher boiling point indicates that the compound has a certain thermal stability, and under normal heating conditions, it is not easy to evaporate. This thermal stability is crucial in the heating process of organic synthesis reactions, ensuring that the compound remains stable within a certain temperature range and participates in the expected reaction.
In terms of density, 1H-pyrazole-4,5-diethyl dicarboxylate is slightly larger than water, about 1.2 g/cm ³. This density characteristic makes it sink to the bottom when mixed with water, and this characteristic can be used in separation and purification operations.

The synthesis method of 1H-pyrazole-4,5-dicarboxylic acid diethyl ester is a key research in the field of organic synthesis. There are many methods, each has its own advantages, and the following is a detailed description of Jun.
First, pyrazole is used as the starting material, an acyl group is added through acylation reaction, and then nucleophilic substitution occurs with halogenated ethyl acetate under the action of alkali, and then the target product is obtained. Although the raw materials are common in this way, the acylation and substitution steps require fine regulation of the reaction conditions, such as temperature, amount of alkali, etc., to obtain the ideal yield.
Second, the cyclization strategy is adopted. Starting with a chain-like compound containing a suitable functional group, a pyrazole ring is cyclized under specific reagents and conditions, and a carboxyl ethyl ester group is introduced. The key to this process lies in the selectivity and yield of the cyclization reaction. Careful selection of catalysts and reaction solvents is required to promote the smooth occurrence of cyclization.
Third, the coupling reaction with the help of metal catalysis. The unique activity of metal catalysts is used to promote the coupling of the substrate containing the pyrazole ring with the reagent containing the carboxyl ethyl ester.

In practical application, when considering the availability of raw materials, the ease of control of reaction conditions, cost and yield and other factors, the optimal synthesis path is carefully selected to achieve the purpose of efficient synthesis.

1H-pyrazole-4,5-dicarboxylic acid diethyl ester is an important intermediate in organic synthesis. During storage and transportation, many matters should be paid attention to.
First, when storing, be sure to choose a dry, cool and well-ventilated place. This compound is afraid of moisture, and moisture can easily cause its hydrolysis and deterioration, which will damage its quality and activity. Therefore, it should be kept away from water sources and places with high humidity. And the temperature should be controlled within an appropriate range. Excessive temperature may cause decomposition or cause other chemical reactions, resulting in damage to its stability.
Second, during transportation, the packaging must be solid and reliable. It should be packed in a sealed container to prevent leakage. Because it may have certain irritation and chemical activity, if it leaks, it will not only be wasted, but also endanger the safety of transportation personnel and the surrounding environment. At the same time, relevant regulations and standards must be followed during transportation to ensure that the transportation conditions are suitable.
Third, whether it is storage or transportation, it should avoid contact with oxidants, acids, bases and other substances. 1H-pyrazole-4,5-dicarboxylate diethyl ester has active chemical properties. When it encounters the above substances, it is prone to violent chemical reactions, leading to serious consequences such as combustion and explosion.
Fourth, storage places and transportation vehicles should be equipped with corresponding emergency treatment equipment and materials. In the event of leakage and other accidents, effective measures can be taken in a timely manner to reduce losses and hazards. If there is an adsorption material, it can absorb leaking liquids; there are fire extinguishing equipment to deal with possible fires.
In short, 1H-pyrazole-4,5-diethyl dicarboxylate needs to be stored and transported from various aspects such as environment, packaging, isolation and emergency response.

In today's world, business conditions are unpredictable, and it is not easy to know the market price of dimethyl 1H-pyrazole-4,5-dicarboxylate. The price is influenced by various factors, such as the abundance of raw materials, the situation of supply and demand, the difficulty of process, and the relaxation of government orders.
At the one end of the raw material, if the source is scarce, the collection is difficult, or the preparation is complicated, the cost will rise, and the price will also be high. Or the sudden change in the output of the origin of the raw material causes the market supply to be unstable, and the price fluctuates.
The way of supply and demand is related to the market price. If there are many applicants and few suppliers, and everyone bids, the price will rise; if there is an oversupply, the stock of goods will be difficult to sell, and the merchant will lose the goods and the price will drop.
The precision of the craftsmanship also affects the cost and quality. Fine craftsmanship can increase production and improve quality. However, if high equipment and rare additives are required, the cost will also rise, and the price will also rise.
Those who issue decrees, either involving environmental regulations or trade barriers, have an impact on production and circulation. Strict environmental protection orders limit production, reduce supply and increase prices; barriers to trade prevent the circulation of goods, and also cause price changes.
And the market fluctuates frequently, changes in current events, and the guidance of public opinion can make prices different in an instant. Therefore, in order to determine the current market price of 1H-pyrazole-4,5-dimethyl dicarboxylate, it is necessary to gather extensive business information, carefully observe the market dynamics, and track in real time to obtain a more accurate price. If you only rely on empty ideas, it is difficult to understand the details.
