Methyl (R)-1,2,3,4-tetrahydro-3-isoquinoline carboxylate

Methyl (R) -1,2,3,4-tetrahydro-3-isoquinoline carboxylic acid ester, its chemical structure is derived from the isoquinoline parent nucleus. Isoquinoline itself is a nitrogen-containing heterocyclic compound. In this structure, 1,2,3,4-tetrahydro indicates that the double bonds at the 1,2,3,4 positions on the isoquinoline ring are hydrogenated and reduced, resulting in the partial saturation of the ring.
And (R) indicates the configuration of the chiral center. The chiral center is usually a carbon atom connected with four different groups, and the configuration of the chiral center in this compound is of the (R) type.
Furthermore, 3-isoquinoline carboxylic acid ester means that there is a carboxylic acid ester group attached to the 3 position of the isoquinoline ring. The carboxylic acid ester group is formed by the esterification reaction of the carboxylic group with methanol, that is, the hydroxyl group of the carboxylic group is replaced by the methoxy group to form the methyl ester structure.
In this way, the chemical structure of methyl (R) -1,2,3,4-tetrahydro-3-isoquinoline carboxylic acid ester combines the characteristics of the partially saturated ring derived from isoquinoline, the specific chiral configuration, and the 3-position carboxylic acid methyl ester group. These structural characteristics play a key role in determining its chemical and biological

Due to the principle of "similarity and miscibility", the molecular structure of the compound has a certain polarity, and it interacts with polar organic solvent molecules and can be dispersed. However, in water, the solubility is relatively weak. Due to the insufficient matching of the polarity of the water molecule with the polarity of the compound, it is difficult to overcome the original intermolecular force and disperse and dissolve.
Furthermore, the density also has its value. The density reflects the compactness of the molecule, which is about [specific value] g/cm ³. This value indicates the distribution of its molecules per unit volume, and density factors affect its delamination and diffusion behavior when mixed with other substances.
In addition, the compound may have a specific odor, which is generated by the evaporation of molecules into the air, stimulating olfactory receptors. Its odor characteristics may be weakly aromatic, which is related to the aromatic structural units contained in the molecule, which evaporate in the air and trigger olfactory perception.

Methyl (R) -1,2,3,4-tetrahydro-3-isoquinoline carboxylic acid ester, although this substance has potential value in the field of medicinal chemistry, the current market prospect is still blurred and chaotic.
In the way of the synthesis of watchers, the process is still complicated, and the cost of raw materials remains high. To prepare on a large scale, technical constraints and economic considerations are obstacles, which discourage many manufacturers. Therefore, large-scale mass production is limited, and the quantity of those circulating in the market is also scarce.
Discuss its application, in the field of innovative drug research and development, or can be used as a key intermediate, providing a possible way for the creation of new drug formulations. However, the road of new drug research and development is full of obstacles and the cycle is long. From laboratory discovery to clinical application, it must be strictly verified many times. Therefore, its practical application in the pharmaceutical field has not been widely spread.
Speaking of market demand, due to the uncertainty of the progress of new drug research and development, it is difficult to accurately estimate the market demand. Buyers are mostly scientific research institutions and pharmaceutical company R & D departments, and the demand is mostly concentrated in a small number of experimental uses.
To sum up, methyl (R) -1,2,3,4-tetrahydro-3-isoquinoline carboxylic acid ester is just like unpolished jade.
