To prepare a compound of 5-hydroxy-2-methoxy-3-methylphenyl, there are various methods. The following are Jun Chen and one or two.
First, a suitable starting material can be used, protected by phenolic hydroxyl groups, and then methoxy groups and methyl groups are introduced. First, benzene compounds containing phenolic hydroxyl groups are taken, and reagents such as tert-butyl dimethylsilyl chloride are used to etherify phenolic hydroxyl groups under the catalysis of bases such as imidazole to obtain protection. Next, methylation reagents such as iodomethane are used to react in a suitable solvent under the action of bases such as potassium carbonate to introduce methoxy groups. Then using similar methylation means, or by means of Fu-gram alkylation reaction, chloromethane and anhydrous aluminum trichloride are used as agents to introduce methyl groups. After the deprotection step, the phenolic hydroxyl group is restored with reagents such as tetrabutylammonium fluoride, and the target product is obtained.
Second, the phenolic hydroxyl group is first constructed by starting with a phenyl ring containing an appropriate substituent. Halogen atoms such as bromine atoms can be introduced by electrophilic substitution of aromatic rings, and then treated with metal-organic reagents such as Grignard reagent or lithium reagent, and then reacted with the corresponding oxygen-containing reagent to introduce methoxy groups. Subsequently, the aldehyde group is introduced by carbonylation reaction, and the aldehyde group is reduced to hydroxymethyl group with a reducing agent such as sodium borohydride, and then oxidized to a carboxyl group. Methyl After the phenolic hydroxyl group is introduced at a specific position in the benzene ring by a suitable method, the 5-hydroxy-2-methoxy-3-methylphenyl compound can be obtained by appropriate modification.
Third, starting from simple benzene derivatives, complex substituents are constructed through multi-step reactions. For example, methoxy groups are introduced first with halogen atoms, and then palladium-catalyzed coupling reactions are used to connect with methyl and hydroxyl precursor reagents. After detailed functional group transformation and modification, the target structure is gradually achieved. For example, the phenyl ring is brominated first, and then methoxy groups are introduced by reacting with methoxylating reagents. The desired 5-hydroxy-2-methoxy-3-methylphenyl compound was formed by coupling with borate esters containing methyl and potential hydroxyl groups through Suzuki reaction and subsequent hydrolysis, oxidation and reduction reactions.

5-Hydroxy-2-methylhydroxy-3-methyl to its physical properties, with the following numbers.
The appearance of this substance may be a colorless and transparent liquid. Under normal temperature and pressure, its texture is relatively uniform, fluidity is quite good, and it is as smooth as a spring. Its smell may have a weak special smell, but it is not pungent and unpleasant. It is like a light and elegant fragrance hidden in the breeze, which needs to be smelled carefully to detect.
When it comes to solubility, it shows good solubility in many organic solvents, such as ethanol, ether, etc., which can be fused with, just like fish and water. It also has a certain solubility in water, but it is slightly less soluble than organic solvents. It is like ink that slowly spreads in water. Although it can be dispersed, it is not completely uniform.
Its boiling point and melting point are important physical properties. The boiling point or in a specific temperature range, this temperature makes it smoothly transform from liquid to gaseous, as if a thing has undergone sublimation. The melting point determines the temperature at which it transforms from solid to liquid, like ice melting in the spring sun. The specific value varies slightly due to the preparation method and purity, but it is roughly within a certain range, just like the stars running on a predetermined orbit.
Density is also a key property. Its density is different or slightly greater than that of water, such as stone sinking in water; or slightly smaller than water, like wood floating in waves, this characteristic is related to its floating and sinking situation in different liquid media.
In addition, its refractive index is also unique. When light passes through this substance, the direction and speed of light propagation will change according to its refractive index, just like light changing its path in a fantasy environment. This property can be used for identification and purity detection, just like a precise ruler to measure its purity.

5-Hydroxy-2-methylamino-3-methylpyridine This substance requires many precautions when storing and transporting.
First, due to its special chemical properties, it has strict requirements on the temperature and humidity of the storage environment. The temperature should be maintained in a specific range. If it is too high, it may cause its chemical structure to change and accelerate decomposition and deterioration; if the humidity is too high, it is easy to cause deliquescence and affect the quality. Therefore, it should be stored in a dry, cool and well-ventilated place.
Second, this substance has certain chemical activity and is contraindicated in compatibility with many other chemicals. Do not co-store and transport with strong oxidants, strong acids, strong alkalis, etc., to prevent violent chemical reactions, such as combustion, explosion and other serious accidents. For example, strong oxidants are encountered, or cause oxidation reactions, releasing a lot of energy and causing dangerous conditions.
Third, the packaging must be tight and reliable. Select suitable packaging materials, such as special plastic or metal containers that are resistant to corrosion, to ensure that they are not damaged and leaked during transportation due to vibration, collision, friction, etc. The name, characteristics, hazard warnings and other information should be clearly marked on the outside of the package, so that the transportation and storage personnel can be clear.
Fourth, the storage and transportation site must be managed by professional personnel. Such people should be familiar with the characteristics of the substance and emergency treatment methods. In the event of an accident such as a leak, it can respond quickly and correctly to reduce the harm. In the event of a leak, the surrounding personnel should be evacuated immediately. After taking protective measures, select an appropriate method to collect and clean up the leak according to its characteristics.
