This is the substance of N1, that is, 2,6-diamino-4- (3-propyl) -1,3-diazanaphthalene-9-ketone (9Ci). Its physical properties are as follows:
Appearance properties or solid, depending on the specific synthesis and processing conditions. Under normal temperature and pressure, or in a stable solid state for storage and transportation. In terms of melting point, it has been determined by many experiments and falls roughly in a specific temperature range. This temperature range is of great significance for its purification and identification, and can help distinguish it from other substances.
Solubility is critical. In common organic solvents, such as ethanol and acetone, or exhibit some solubility, while in water, the solubility may be limited. This property is crucial in its separation, purification and related chemical reaction operations, and can be used to select the appropriate solvent to achieve the best reaction or separation effect.
Density is related to practical application and packaging and transportation considerations. After accurate measurement, the density is an exact value, which reflects its unit volume mass. It is of great significance for the design of reaction vessels, the measurement of reactants and the planning of product packaging specifications.
Stability is also a major point. Under normal environmental conditions, the properties of this substance are relatively stable. When exposed to high temperatures, strong acids and bases or specific strong oxidants and reducing agents, or chemical reactions occur, the structure and properties are changed. Therefore, when storing and using, it is necessary to avoid such adverse conditions in order to maintain its chemical integrity and functional properties.

N1, also known as 1-diethyl-2,6-dimethyl-4- (trifluoromethyl) -1,3-catechol (9Ci), is an organic compound. Its chemical properties are unique and valuable for investigation.
First of all, because its structure contains phenolic hydroxyl groups, it has a certain acidity. The hydrogen atom of the phenolic hydroxyl group can be partially ionized, and in a suitable alkaline environment, it is easy to react with bases to form corresponding phenolic salts. The acidity is affected by the substituents on the benzene ring. Substituents such as dimethyl and trifluoromethyl will change the electron cloud density of the benzene ring, which in turn will affect the acidity of the phenolic hydroxyl group.
Secondly, the benzene ring structure of the compound imparts aromaticity, enabling it to undergo a variety of aromatic electrophilic substitution reactions. Since there are already substituents on the benzene ring, the position selectivity of the electrophilic substitution reaction is controlled by the localization effect of the substituent. For example, dimethyl is an ortho-and para-locator group, and trifluoromethyl is an meta-locator group. The combined influence of these substituents determines the main position where the electrophilic reagent attacks the benzene ring.
Furthermore, the alkyl part of the molecule can undergo free radical substitution reactions. Under conditions such as light or peroxide, the hydrogen atom on the alkyl group can be captured by the free radical, generating the corresponding alkyl radical, and then reacting with other free radicals or reagents.
In addition, due to the fluorine atom, the compound exhibits unique physical and chemical properties. Fluorine atoms have large electronegativity, which can enhance molecular polarity and affect its solubility and stability. At the same time, fluorine-containing groups can play a special role in some chemical reactions, changing the reaction path and product selectivity.
In short, N1-diethyl-2,6-dimethyl-4- (trifluoromethyl) -1,3-quinone has potential applications in organic synthesis, materials science and other fields due to its unique structure.

To obtain (9Ci) of (N1, N1 - diethyl - 2,6 - diisopropyl - 4 - (trifluoromethyl) - 1,3 - catechol), the method can be as follows.
First take appropriate starting materials, such as benzene compounds containing corresponding substituents. Starting with benzene derivatives with diethyl substituents, under specific reaction conditions, 2,6 - diisopropyl groups are introduced. This step can be achieved by electrophilic substitution of halogenated alkanes with benzene rings under the action of appropriate catalysts. If the benzene derivative is reacted with halogenated isopropane, catalyzed by Lewis acid catalysts such as aluminum trichloride, and heated in a suitable organic solvent such as dichloromethane, the isopropyl group can be introduced into the 2,6 position of the benzene ring.
Then, trifluoromethyl is introduced into the 4 position of the benzene ring. This can be carried out in a suitable reaction system by reagents containing trifluoromethyl, such as trifluoromethylation reagents. For example, a transition metal-catalyzed trifluoromethylation reaction can be used. Metal catalysts such as palladium and copper are used with corresponding ligands to react the trifluoromethylation reagent with benzene derivatives that already contain diethyl and diisopropyl groups under basic conditions to achieve the introduction of 4-position trifluoromethyl.
Finally, the corresponding substituent on the phenyl ring is converted into a phenolic hydroxyl group through appropriate oxidation or other functional group conversion reactions to obtain the target product (N1, N1-diethyl-2,6-diisopropyl-4 - (trifluoromethyl) -1,3-catechol). It is necessary to pay attention to the control of the conditions of each step of the reaction, including temperature, reaction time, and the proportion of reactants, etc., to ensure the high efficiency and selectivity of the reaction, and to improve the yield and purity of the product.

I look at this N1 thing, called diisopropyl-2,6-di-tert-butyl-4- (trifluoromethyl) -1,3-naphthalene diphenol (9Ci), when using, many things need to be paid attention to.
First, this material is chemically active, and it must follow the standard process when operating. Because its structure contains special groups, such as trifluoromethyl, which are chemically active and may react violently in case of specific substances, the operating environment must be clean, free of impurities, and the equipment used needs to be pre-treated to ensure purity.
Second, it is related to storage. It should be placed in a cool, dry and well-ventilated place. Diisopropyl, di-tert-butyl and other groups, in high temperature, humid environment, or the stability of the material is affected, or even deteriorated, losing its original characteristics, so the storage conditions must be strictly controlled.
Third, safety protection must not be ignored. During operation, it is necessary to wear suitable protective equipment, such as gloves, goggles, protective clothing, etc. Due to its chemical properties, or the risk of irritation or damage to the skin, eyes and respiratory tract, good protection can ensure the safety of the operator.
Fourth, when taking it, the dosage is accurate. This substance has high chemical activity, dose deviation, or very different reaction results, which affect the experimental or production process. Therefore, the accuracy of the measuring equipment must meet the requirements, and the operation should also be meticulous.
In short, with this N1 bis isopropyl-2,6-di-tert-butyl-4- (trifluoromethyl) -1,3-naphthalenediol (9Ci), all details need to be paid attention to in order to ensure safety and achieve the expected effect.
