Ethyl 2- [ (3-benzodioxol-5-ylcarbonyl) amino] -4, 5-dimethylthiophene-3-carboxylate, is an organic compound. Its physical and chemical properties are as follows:
Looking at its morphology, under room temperature and pressure, it is mostly a solid state. However, the exact state may vary depending on the purity and crystallization conditions.
On its melting point, this is one of the important parameters for identifying compounds. Although the exact melting point value is not detailed, different preparation methods, purity and other factors can cause the melting point to fluctuate.
In terms of solubility, it may exhibit different solubility characteristics in organic solvents. Common organic solvents such as ethanol, acetone, dichloromethane, etc., may have certain solubility. In ethanol, or due to intermolecular forces, it is partially soluble and can form a homogeneous solution. Because the structure of the compound contains polar groups, it interacts with the polarity of ethanol. In dichloromethane, due to its non-polar environment, the solubility of the compound may also be affected by the hydrophobic part of the molecular structure, and there is a certain degree of dissolution.
As for its chemical stability, the groups such as benzodioxane and thiophene in the structure give it unique chemical properties. The benzodioxane part is relatively stable, but under strong oxidation or strong reduction conditions, it may also react. Although the thiophene ring has certain aromatic properties, its electron cloud distribution is different from that of the benzene ring. Under certain conditions, reactions such as electrophilic substitution may occur. Its ester group is easily hydrolyzed in case of strong acid or strong base. Under acidic conditions, it hydrolyzes to form corresponding carboxylic acids and alcohols; under alkaline conditions, it hydrolyzes more rapidly to form carboxylic salts and alcohols. The amide bond part may also be hydrolyzed in high temperature, strong acid or strong base environment, and breaks to form corresponding amines and carboxylic acids.

I don't know the price range of "ethyl + 2 - [ (1,3 - benzodioxol - 5 - ylcarbonyl) amino] -4,5 - dimethylthiophene - 3 - carboxylate" in the market. This is a rather professional chemical substance, and its price is affected by many factors.
First, the purity has a great impact. If the purity is very high, it can be used for high-end scientific research experiments, and the price is high; if the purity is slightly lower, it is only suitable for general industrial use, and the price is slightly lower.
Second, the yield is also the key. If the preparation process of this product is complicated and the output is rare, the so-called "rare is expensive", the price will be high; if the preparation process is relatively simple, the output will be considerable, and the price will be close to the people.
Third, market demand also affects its price. If there is strong demand for this product in many industries and limited supply, the price will rise; if there is little demand and sufficient supply, the price may fall.
Fourth, supplier differences also lead to different prices. Different suppliers have different cost structures and different pricing strategies, so prices may fluctuate.
However, I have not found detailed information on the exact price range, so it is difficult to answer accurately. For more information, please consult chemical product suppliers, relevant chemical trading platforms, or industry professionals, who may be able to provide more accurate price information.
