2-Thiophene formaldehyde, 5-cyano- (6CI, 7CI) is an organic compound. Its physical properties are related to the morphology, melting and boiling point, solubility and other characteristics of this substance, and are extremely important in the fields of chemical industry and scientific research.
This substance may be a solid under normal conditions. Due to the cyanogen group and thiophene ring structure, intermolecular forces or cause it to appear solid. Its melting point and boiling point are affected by molecular structure. Cyanyl groups have strong polarity, which can enhance intermolecular forces and increase the melting boiling point. The conjugated structure of thiophene rings also affects molecular stability and force. According to the structure speculation, the melting point may be in a relatively high range, and more energy is required to overcome intermolecular forces and cause lattice damage.
In terms of solubility, the compound is slightly soluble in water due to its polar cyanyl group. Water is a polar solvent, and the polar cyanyl group can form a certain interaction with water molecules, but the thiophene ring is a non-polar part, which limits its dissolution in water. In organic solvents, such as ethanol, acetone and other polar organic solvents, because it has both polar and non-polar parts, or has good solubility. Because the polar part of the organic solvent can interact with the cyanyl group, the non-polar part interacts with the thiophene ring, which is conducive to dissolution.
In addition, the density of the compound may vary depending on the molecular structure and relative molecular weight. Due to the presence of sulfur, nitrogen and other atoms, the relative molecular weight is large, and the structure is compact, and the density may be higher than that of common hydrocarbon compounds
In conclusion, the physical properties of 2-thiophenylformaldehyde, 5-cyano- (6CI, 7CI) are determined by its unique molecular structure, which is of great significance for its application in various fields.

2-Thiophene formaldehyde, 5-cyano (6CI, 7CI), there are many methods for synthesis, which is described by you today.
One method is to use 5-bromo-2-thiophene formaldehyde as the starting material. Shilling it and cuprous cyanide in a suitable solvent, such as N, N-dimethylformamide (DMF), at a certain temperature, co-heating. Cyanyl can replace bromo, and then obtain the target product. This reaction requires precise temperature control, and cuprous cyanide is highly toxic, and the operation should be extremely cautious.
There are 2-thiophene carboxylic acid as the starting point. It is first converted into an acyl chloride, which can be co-heated with thionyl chloride. Then the acyl chloride reacts with sodium cyanide in a suitable solvent, such as dichloromethane, to form 2-thiophenoformonitrile. After being reduced at low temperature by a specific reducing agent, such as diisobutylaluminum hydride (DIBAL-H), the nitrile group can be converted into an aldehyde group, and the final product is 5-cyano-2-thiophenylformaldehyde.
There is also a method of synthesis from thiophene through multi-step reaction. First, thiophene is acylated with suitable reagents, such as oxalyl chloride and aluminum trichloride, to obtain 2-thiophenoformyl chloride. The subsequent steps are similar to those started from 2-thiophenecarboxylic acid above, first forming nitrile and then reducing to aldehyde.
All synthesis methods have advantages and disadvantages. From the availability of raw materials, the difficulty of reaction, the yield and the safety of operation, all need to be weighed. When synthesizing, we must choose the best method according to the actual situation to achieve twice the result with half the effort.
