This is a 1:1 compound formed by (Ar) -A-hydroxyphenylacetic acid and (1R, 2S) -2- (3,4-difluorophenyl) cyclopropylamine. Its chemical structure is described as follows:
First, (Ar) -A-hydroxyphenylacetic acid, which is connected to an acetic acid group on one side of the benzene ring, and a hydrogen on the methylene group connected to the benzene ring is replaced by a hydroxyl group. The benzene ring is a six-membered carbon ring with a conjugated large π bond, which is very stable. The acetic acid group is formed by linking a methyl group to a carboxyl group, which is acidic and can participate in many chemical reactions. The presence of this hydroxyl group makes the compound have the properties of both an alcohol hydroxyl group and a carboxyl group, and can undergo esterification and oxidation reactions.
Let's talk about (1R, 2S) -2- (3,4-difluorophenyl) cyclopropane, which means that there is a 3,4-difluorophenyl group attached to the cyclopropane ring at position 2, and an amino group attached to the cyclopropane at position 1. Cyclopropane ring is relatively active and easy to open ring due to high bond angle tension. In 3,4-difluorophenyl group, fluorine atoms have strong electron absorption, which will affect the electron cloud density of the benzene ring and change its chemical activity. Amino groups are basic and can react with acids to form salts.
When the two form compounds at a 1:1 ratio, they usually form an amide bond through a condensation reaction between carboxyl and amino groups. This structure endows the compound with unique chemical and physical properties, which may be of great significance in the fields of organic synthesis and medicinal chemistry, because amide bonds widely exist in many bioactive molecules and drugs.

A compound formed by (Ar) -A-hydroxy-phenylacetic acid and (1R, 2S) -2- (3,4-difluorophenyl) cyclopropylamine (1:1), this compound has specific physical properties. It is usually white to off-white crystalline powder, odorless by smell and tasteless by taste. The melting point is within a certain range, due to precise synthesis and structural influence, about [X] ℃ - [X + Delta X] ℃.
In terms of solubility, the compound has a certain solubility in organic solvents such as ethanol and acetone, indicating that it has a certain fat solubility. The dissolution in water is slightly inferior. Due to the coexistence of polar and non-polar structures within the molecule, its hydrophilic and hydrophobic properties are balanced, resulting in limited solubility in water.
In terms of stability, under normal environmental conditions, if it avoids strong light, hot topics and high humidity, the compound has stable properties and is not easy to change its structure. However, when encountering strong acids, strong bases or strong oxidants, due to the presence of active groups such as hydroxyl groups and amine groups in the molecule, it is easy to undergo chemical reactions and cause structural changes.
Density and other physical parameters also have characteristics. The density is about [X] g/cm ³, which reflects the degree of tight accumulation and relative mass distribution of its molecules. It is of great significance for its behavior and technological application in different media. The above properties have a profound impact on their application in the fields of medicine and chemical industry, such as pharmaceutical synthesis, where their solubility and stability affect preparation and drug release; in chemical production, density and melting point affect separation and purification processes.
