Methyl 2-bromo-4-fluorobenzo[d]thiazole-6-carboxylate

Methyl 2-bromo-4-fluorobenzo [d] thiazole-6-carboxylic acid ester, this is an organic compound with unique physical properties.
Looking at its properties, it is a crystalline solid under normal conditions. Due to the orderly arrangement of atoms in the molecule, the lattice structure is regular, and it presents a crystalline state.
Its melting point has attracted much attention, which is the embodiment of intermolecular forces and lattice energy. Because the molecule contains bromine, fluorine and other halogen atoms and ester groups, the halogen atom has high electronegativity, which can enhance the intermolecular force; the ester group also participates in the intermolecular interaction, so its melting point or relatively high, so the molecule needs more energy to overcome the lattice binding and realize the transition from solid to liquid.
In terms of solubility, the compound has good solubility in organic solvents. There are similar interactions between molecules of organic solvents and target compound molecules, such as van der Waals force, dipole-dipole interaction, etc. It contains aromatic rings, halogen atoms and ester groups, etc. The aromatic rings have certain hydrophobicity, and the halogen atoms and ester groups can participate in specific interactions, making the compound more soluble in halogen-containing organic solvents such as dichloromethane and chloroform, and polar organic solvents such as acetonitrile and acetone. However, the solubility in water is not good, because the non-polar part is large, and it is difficult to form strong interactions between water molecules and the compound molecules. The hydrogen bond between water molecules is weak, which does not match the principle of "similar miscibility".
Its density is closely related to the molecular weight and the degree of molecular accumulation. Due to the bromine atom, the relative atomic weight of bromine is large, which increases the molecular weight; and the molecular structure is compact, which increases the mass per unit volume, so the density may be higher than that of common organic compounds.
In addition, the volatility of this compound is low. The strong intermolecular force restricts the escape of molecules from the liquid surface. In addition, the molecular weight is large, and it is less volatile. It can maintain a relatively stable solid or liquid state at room temperature and pressure.
