4-Aminoacetophenone CAS 99-92-3

Cough suppressant is an artificially synthesized β ₂ receptor agonist with strong and persistent bronchodilator effects. It is clinically used to treat diseases such as bronchial asthma, asthmatic bronchitis, chronic bronchitis, and emphysema. 4-Aminoacetophenone is a key intermediate in the synthesis of cough suppressant. Through a series of chemical reactions such as nitration, reduction, coupling, etc., it can be converted into cough suppressant molecules. In this process, its amino and ketone groups play an important role, gradually constructing the core structure of cough suppressant molecules through reactions with different reagents. In addition to cough suppressant, 4-Aminoacetophenone can also be used to synthesize various other drugs. 

Antiviral drugs are important means to treat viral infectious diseases. With the continuous mutation and evolution of viruses, the efficacy of traditional antiviral drugs gradually decreases, making the development of new antiviral drugs an important task in the current pharmaceutical field. 4-Aminoacetophenone, as a compound with a unique chemical structure, has demonstrated potential application value in the development of antiviral drugs. Cardiovascular disease is one of the leading causes of death worldwide. It is of great significance to develop efficient and safe cardiovascular drugs to reduce the incidence rate and mortality of cardiovascular diseases. As a compound with multiple biological activities, it has demonstrated potential application value in the development of cardiovascular drugs. It can also serve as a starting material or intermediate for the synthesis of certain cardiovascular drugs. For example, drug molecules with vasodilation and blood pressure lowering effects can be constructed by introducing specific functional groups such as ester and amide groups into their molecules. These drug molecules can regulate the vasomotor state of blood vessels by binding to receptors on vascular smooth muscle cells, thereby improving cardiovascular function.

Some insecticides based on 4-Aminoacetophenone have shown good killing effects on Lepidoptera pests. For example, by introducing specific substituents into its molecules, it can enhance its stomach toxicity and contact killing effects on Lepidoptera insect larvae. These compounds can cause the death of pests by interfering with their nervous or respiratory systems. In field experiments, this type of insecticide has a high control effect on common lepidopteran pests such as cotton bollworm and cabbage caterpillar, and is relatively safe for crops. 4-Aminoacetophenone based insecticides have also demonstrated unique advantages for piercing sucking mouthparts pests such as aphids and whiteflies.

It can be used to synthesize fungicides against various fungal diseases. By introducing specific functional groups such as sulfonamide and triazole groups into its molecules, it is possible to enhance its destructive effect on fungal cell walls or inhibit fungal respiratory metabolism processes. These fungicides have good control effects on common fungal diseases such as wheat rust, rice sheath blight, and apple scab. In addition to being effective against fungal diseases, fungicides based on 4-Aminoacetophenone also have certain preventive and therapeutic effects on certain bacterial diseases. Through structural optimization, compounds with inhibitory activity against plant pathogenic bacteria can be developed, providing a new option for the prevention and control of plant bacterial diseases. 

It may have a promoting effect on plant growth. They can promote plant growth and development by regulating hormone balance within the plant, affecting cell division and elongation. For example, using plant growth regulators containing 4-Aminoacetophenone derivatives on certain crops can increase plant height, stem thickness, and leaf area, and improve crop yield. In addition to promoting growth, 4-Aminoacetophenone derivatives may also enhance plant stress resistance. They can induce plants to produce some stress related proteins, enhancing their resistance to adversity such as drought, low temperature, and salinity. For example, under drought conditions, the use of plant growth regulators containing 4-Aminoacetophenone can reduce water evaporation in plants and improve their drought resistance. The derivative of this substance can work synergistically with other plant growth regulators to achieve better results. For example, when combined with auxin substances, it can promote the development of plant roots and nutrient absorption; When combined with cytokinins, it can promote cell division and proliferation, improve plant growth rate and quality.

UV absorbing dyes play an important role in protecting materials from UV radiation damage. It can introduce functional groups with ultraviolet absorption through specific chemical reactions, such as reacting with compounds containing carbonyl, cyanide, and other functional groups. For example, dyes with high UV absorption properties can be synthesized by reacting with compounds containing benzotriazole structures. This type of dye is widely used in fields such as plastics, coatings, textiles, etc. It can effectively prevent materials from aging and discoloration due to ultraviolet radiation. Photogenic dyes have important application value in photolithography technology, optical storage, and other fields. Dye molecules with photosensitive properties can be formed through photochemical reactions or by combining with other photosensitive groups. For example, under light conditions, 4-Aminoacetophenone derivatives can undergo photolysis reactions, producing free radicals or other active intermediates, thereby triggering chemical reactions and achieving information recording and storage. 

In the manufacture of perfume, it can be used as one of the important perfume ingredients. Its unique fragrance can add a special lingering charm to perfume, making its fragrance more rich and lasting. Various perfume with different styles and fragrance types can be prepared by reasonable blending with other spice ingredients to meet the needs of different consumers. For example, in some flower scented perfume, they can also be combined with rose, jasmine and other floral components to enhance the floral flavor of perfume, making it more fresh and elegant; In some oriental perfume, it can be combined with sandalwood, musk and other ingredients to create a mysterious and charming aroma atmosphere.

Floral flavor is an important category in the fragrance industry, which is widely used in perfume, cosmetics and other fields. Using 4-Aminoacetophenone as raw material, fragrances with floral characteristics can be synthesized through a series of chemical reactions. For example, by condensing it with compounds such as benzaldehyde and acetaldehyde, an intermediate with a jasmine fragrance can be generated. After further reduction, esterification, and other reactions, a fragrance with a strong jasmine fragrance can be obtained. This perfume can be used in combination with other floral ingredients to prepare floral perfume, so that perfume has a realistic jasmine fragrance.
