6-Methoxy-2,3-pyridinediamine, this is an organic compound. Its physical properties are unique, let me explain in detail.
Looking at its properties, it is either a solid state under normal conditions, and a white to slightly yellow powder. This is due to the characteristics of the molecular structure, which causes it to reflect and absorb light.
When it comes to the melting point, it is in a specific temperature range, which is crucial for the transformation of its physical state. Due to the intermolecular forces, at this temperature, the lattice structure begins to disintegrate, gradually melting from a solid state to a liquid state.
In terms of solubility, it varies in common organic solvents. In some polar organic solvents, such as ethanol, there may be a certain solubility. This is because the polarity of ethanol interacts with some groups of the compound, so that the molecules can be dispersed in the solvent; in non-polar solvents, such as n-hexane, the solubility is extremely low, because it is difficult to attract and fuse with the compound due to its non-polar structure.
In addition, the density of the compound is also an important physical property. The density reflects the compactness of its molecular stacking and is affected by the size, shape and mutual arrangement of the molecules. Its density data is of great significance for applications in the chemical industry, materials and other fields, and is related to the process design of mixing and separation of substances. < Br >

To prepare 6-methoxy-2,3-pyridine diamine, the method is as follows:
First, a suitable pyridine derivative is used as the starting material, and this derivative needs to have a specific substituent to lay the foundation for the subsequent reaction. If a pyridine containing an appropriate substituent is selected, the substituent at a specific position will be gradually converted into the desired group of the target product in the subsequent reaction.
Then, the etherification reaction can be applied. Choose a suitable etherification reagent, and under appropriate reaction conditions, introduce the methoxy group at a specific position of the pyridine derivative. This reaction requires temperature control, time control, and the selection of suitable solvents and catalysts to promote the efficient progress of the reaction. For example, with a certain etherification agent, in an organic solvent, in a certain temperature range, catalyzed by a certain catalyst, the methoxyl group can be successfully integrated into the pyridine ring after several times.
Then, proceed to the amination step. Select an appropriate amination reagent, and introduce an amine group at another specific position in the pyridine ring through a specific reaction path. This process also requires fine regulation of the reaction conditions, such as reaction temperature, reaction time, and reactant ratio, to ensure that the amination reaction occurs precisely at the target location and the product purity is up to standard.
In addition, after each step of the reaction, the method of separation and purification is required to remove impurities to obtain a pure intermediate or final product. By means such as extraction, distillation, recrystallization and column chromatography, the products and impurities can be effectively separated according to their physical and chemical properties. In this way, 6-methoxy-2,3-pyridinediamine can be obtained through multi-step reaction and purification operations.

The market price range of 2,3-pyridinediamine, 6-methoxy-is difficult to determine immediately. The price of this compound often varies due to many factors.
First, the source is related to the price. If it is purchased from a common and numerous supplier, or due to competition, the price is slightly lower; however, if it is obtained from a specific and rare source, the price must be high.
Second, the difference in purity has a great impact. The high purity of "2,3-pyridinediamine, 6-methoxyl-" is difficult to prepare, the process is complicated, and the cost is huge, so its price is high; while the purity is slightly inferior, the price may be low.
Third, the market supply and demand situation is the key. If there are many applicants, but there are few suppliers, the price will rise; if the supply exceeds the demand, the price will decline.
Fourth, the number of batches also affects the price. For bulk purchases, merchants may make profits due to large quantities, and the unit price is low; for small purchases, the cost of merchants is not easy to dilute, and the unit price may be high.
As far as I know, there is currently no conclusive price range to inform. If you want to know the details, you can go to the chemical trading market and relevant e-commerce platforms to consult suppliers, and you will be able to get a closer price range.
