4H-pyrano [3,2-g] furan-2,8-dicarboxylic acid, 9-methyl-6,9-dioxo-4,6-dioxo-10-propyl This compound has several physical properties. Its appearance is often in a specific crystalline form, and the crystal structure depends on intermolecular interactions, which maintain the orderly arrangement of crystals.
In terms of solubility, due to the fact that its molecules contain multiple polar carboxyl groups, oxygen atoms and other groups, it exhibits certain solubility in polar solvents (such as water and alcohols). The carboxyl group can interact with water molecules through hydrogen bonds to promote partial dissolution; however, the long carbon chain and cyclic structure in the molecule limit the solubility, so it is not very soluble in water. In non-polar solvents (such as alkanes), the solubility is relatively poor, due to the mismatch between molecular polarity and non-polar solvents, and the intermolecular forces are difficult to effectively overcome the intermolecular forces of solvents. The melting point of
is also an important physical property. Interactions such as hydrogen bonds and van der Waals forces exist between the molecules of the compound, which give strong intermolecular binding forces. To transform the compound from a solid state to a liquid state, sufficient energy needs to be provided to break these effects, so the melting point is relatively high. The exact melting point value depends on the specific structure of the molecule and the crystalline purity. The higher the purity, the closer the melting point is to the theoretical value. The boiling point of
is also worthy of attention. The boiling point is closely related to the intermolecular force and the relative molecular weight. This compound has a relatively large molecular weight and rich intermolecular force, so it requires more energy to break free from the intermolecular binding during boiling, and the boiling point is higher. However, since the compound may decompose before reaching the boiling point, the actual determination of the boiling point may need to be carried out under special conditions.
In addition, the compound may have certain optical properties. For example, due to the asymmetry of the molecular structure, it may exhibit optical rotation, which can deflect the vibration direction of polarized light. The specific direction and degree of optical rotation depend on the three-dimensional configuration of the molecule.

This compound has specific physical and chemical properties. From a structural perspective, the core structure of its pyridyl-phenanthrene gives it certain stability and conjugation properties. Among them, the dicarboxylic acid group at the 2,8-position is acidic due to the presence of carboxyl groups, and can neutralize with bases to form corresponding carboxylate. This carboxyl group can also participate in the esterification reaction, forming ester compounds with alcohols under appropriate catalysts and conditions. This reaction is often used in organic synthesis to introduce specific functional groups or change the solubility and reactivity of molecules.
9-position ethyl and 10-position propyl, as alkyl substituents, add a certain degree of hydrophobicity to the molecule. The presence of alkyl groups affects the spatial configuration and electron cloud distribution of molecules, which in turn affects their interactions with other molecules. For example, in non-polar solvents, the solubility of the compound may be enhanced due to the hydrophobic action of alkyl groups.
6,9-dioxy and 4,6-dioxide moiety have a significant impact on the electronic structure and reactivity of molecules. The electronegativity of oxygen atoms changes the density of the surrounding electron cloud, resulting in changes in the reactivity of neighboring atoms. These oxygen-containing functional groups may participate in redox reactions, or participate in electron transfer processes as electron receptors, and may have potential applications in fields such as organic optoelectronic materials.
