4,5-Diaminodiacetic acid is an important compound in organic chemistry. Its physical properties are quite unique, let me tell them one by one.
Looking at its properties, under normal circumstances, 4,5-diaminodiacetic acid is mostly in the state of white crystalline powder. This form makes its appearance pure, the particles are delicate, and a fine luster can be seen under light, just like fine crystal jade.
When it comes to solubility, this compound exhibits a certain solubility in water. When placed in an appropriate amount of water, after stirring, it can gradually dissolve to form a clear or slightly cloudy solution. However, it is not easily soluble in organic solvents, such as ethanol, ether, etc., and is mostly suspended or precipitated in such solvents, making it difficult to melt with solvents.
In addition to the melting point, the melting point of 4,5-diaminodiacetic acid is relatively high, and it needs to reach a specific temperature to melt into a liquid state. This melting point characteristic indicates that the intermolecular force is strong, the structure is relatively stable, and it needs to supply more energy to change its solid state.
4,5-diaminodiacetic acid has a moderate density, which is similar to that of common organic compounds. In practical operation and application, this density characteristic affects its distribution and settlement behavior in different media.
In terms of its odor, it usually has a weak and special smell, which is not pungent and unpleasant. However, its unique smell can still be sensed under a fine smell. This smell originates from the chemical properties of its molecular structure.
In addition, 4,5-diaminodiacetic acid is relatively stable chemically at room temperature and pressure. However, when it encounters extreme conditions such as strong acids, strong bases, or specific high temperatures and high pressures, chemical reactions may occur, causing its structure and properties to change.

4,5-Dimethylglutaric acid is a class of organic compounds. Its chemical properties are quite unique and acidic, because the molecule contains a carboxyl group. The carboxyl group can release protons under suitable conditions, exhibit acidic properties, and can react with bases to form corresponding salts and water. For example, when reacted with sodium hydroxide, 4,5-dimethylglutaric acid and water are formed.
The carbon chain structure in the molecule of 4,5-dimethylglutaric acid gives it certain physical properties and reactivity. Due to the presence of methyl groups, the spatial structure of the molecule and the distribution of electron clouds are affected. Methyl is an electron-supplying group, which can increase the electron cloud density of the carbon atoms connected to it, and then have a fine-tuning effect on the acidity of the carboxyl group.
In the field of organic synthesis, 4,5-dimethylglutaric acid can be used as an important synthesis intermediate. With the activity of its two carboxyl groups, it can participate in many reactions, such as esterification with alcohols to form corresponding esters. Such esters may have application value in industrial fields such as fragrances and coatings. At the same time, the carbon chain part of its molecular structure can also provide diversified possibilities for subsequent reactions, such as the extension of carbon chains or the conversion of functional groups, so as to construct more complex organic molecular structures.

4,5-Dimethylpyrimidine-2,6-dicarboxylic acid is a key intermediate in organic synthesis and is widely used in many fields such as medicine and pesticides. Its synthesis methods are diverse, and the following are common ones:
###Using diethyl malonate and its derivatives as starting materials
Diethyl malonate and corresponding halogenated hydrocarbons undergoes alkylation to obtain alkylated diethyl malonate. This product is then cyclized with guanidines under suitable conditions to form a pyrimidine ring. For example, diethyl malonate first interacts with iodomethane to obtain a methylation product, and then reacts with guanidine under the catalysis of a base to obtain 4,5-dimethylpyrimidine-2,6-dicarboxylic acid through cyclization. The raw materials of this route are easy to obtain, and the reaction steps are relatively clear. However, there may be side reactions during the alkylation process, and the yield is limited.
###Through the functional group transformation of pyrimidine derivatives
, suitable pyrimidine derivatives can be found. The structure is similar to the target product, and only specific functional groups need to be transformed. For example, some pyrimidine derivatives with groups that can be oxidized to carboxylic groups can oxidize the side chain functional groups to carboxylic groups by suitable oxidants, such as potassium permanganate, etc., to achieve the synthesis of 4,5-dimethylpyrimidine-2,6-dicarboxylic acid. The advantage of this method is that the starting material or the pyrimidine skeleton is already available, and the key is precise functional group transformation, but the choice of reaction conditions and oxidants is strict to avoid damage to the pyrimidine ring.
###Adopting a multi-component reaction strategy
Multi-component reaction is the one-step reaction of multiple raw materials in the same reaction system to build complex molecules. Using aldehyde, ketone, urea (or guanidine) and malonic acid as raw materials, 4,5-dimethylpyrimidine-2,6-dicarboxylic acid was directly synthesized by multi-component reaction under specific catalyst and reaction conditions. This strategy has high atomic economy, simple steps, and can effectively shorten the synthesis route. However, the regulation of reaction conditions is quite difficult, and factors such as the ratio of raw materials, the type and dosage of catalysts need to be carefully optimized to obtain the ideal yield and selectivity.

In today's world, the business market is complex and prices are changeable. However, if you want to investigate the price range of 4,5-diaminodibenzoic acid in the market, you need to consider various factors in detail.
This 4,5-diaminodibenzoic acid is useful in many fields such as chemical industry and medicine. Its price often varies due to quality, purity, supply and demand.
If it is of high quality and high purity, the price must be very high. The cost of production in the market is often increased due to the difficulty of preparation and the complexity of the process, so its price may be as high as tens of gold per gram.
The situation of supply and demand is also the main reason. If there are many people who ask for it, and there are few people who supply it, the price will rise; on the contrary, if the market is full of goods and there are few people who need it, the price may be downward.
Generally speaking, in an ordinary market, the price of 4,5-diaminodibenzoic acid per gram may be between a few gold and a few tens of gold. However, this is only an approximate number. The actual price will vary according to the situation, quality, supply and demand. If you want to get an accurate price, you need to carefully check the market conditions and consult all merchants.
