N6-[(3,4-Dichlorophenyl)methyl]-N6-nitroso-2,4,6-quinazolinetriamine

N6-[(3,4-Dichlorophenyl)methyl]-N6-nitroso-2,4,6-quinazolinetriamine, commonly known as DCPTA, is a synthetic chemical compound that belongs to the class of quinazoline derivatives. It is used in plant biology research as a plant growth regulator to promote cell division and elongation in plants. DCPTA has also been used as a fungicide, herbicide, and insecticide. The chemical formula of DCPTA is C18H18Cl2N6O, and it has a molecular weight of 423.29 g/mol. It is a yellowish-white solid that is soluble in water and has a melting point of 163-165°C. DCPTA is highly potent and requires careful handling due to its potential toxicity. The mechanism of action of DCPTA involves the activation of the plant hormone, auxin, which promotes cell division and elongation in plants. It works by inhibiting the degradation of auxin, which results in an increased concentration of auxin in the plant cells, leading to the stimulation of plant growth. While DCPTA has shown promising results in plant growth regulation, its use is restricted due to its potential toxicity. It has been reported to cause skin and eye irritation, and respiratory problems if inhaled. Therefore, it is important to handle DCPTA with caution and to follow appropriate safety measures when working with this chemical.
