What are the physical properties of 6-chloro-2-iodo-1h-purine?
6-Chloro-2-iodine-1H-purine is an organic compound with unique physical properties, which is of great significance to chemical researchers.
The appearance of this compound may be in a solid state. Due to the presence of halogen atoms such as chlorine and iodine, the intermolecular force is enhanced, resulting in a relatively high melting point. Specifically, the electronegativity of chlorine and iodine atoms makes the molecules have strong polarity, and there is a dipole-dipole force between molecules, thereby increasing the melting point. However, due to the lack of a wide hydrogen bond network, the melting point may not be too high, roughly in the range of melting points of common organic solids, about tens to hundreds of degrees.
Its boiling point is also affected by the intermolecular force. In view of molecular polarity, more energy is required to overcome intermolecular attraction to achieve gasification, so the boiling point may be higher, but the exact value depends on the details of molecular structure and the complexity of intermolecular forces.
The solubility of 6-chloro-2-iodine-1H-purine in common organic solvents is worthy of investigation. Due to its polar nature, it is more soluble in polar organic solvents such as dimethyl sulfoxide (DMSO) and N, N-dimethylformamide (DMF). Due to the principle of "similar miscibility", polar molecules are easily soluble in polar solvents. However, in non-polar organic solvents such as n-hexane and benzene, the solubility may be poor because of its weak interaction with non-polar solvents.
The density of this compound is related to the molecular weight and the way of molecular packing. Atoms containing relatively large atomic weights such as chlorine and iodine have an increase in molecular weight. If the molecular packing in the crystal structure is tight, the density or larger, it is greater than the density of common organic compounds.
The physical properties of 6-chloro-2-iodine-1H-purine are determined by the types of atoms and the connection mode in its molecular structure, and these properties are extremely critical for their applications in chemical synthesis, drug development and other fields.
