1 - (p-toluenesulfonyl) - 2,5 -dihydropyrrole, this is an organic chemical. The study of its stability depends on its structure, environmental conditions and other factors.
In terms of structure, the compound contains a pyrrole ring, and the double bond in the ring endows it with a certain reactivity. The p-toluenesulfonyl group is connected to the pyrrole ring, and this group has an electron-absorbing effect, or affects the electron cloud distribution of the pyrrole ring, which in turn affects the stability. Generally speaking, electron-withdrawing groups can reduce the density of the ring electron cloud, causing its electrophilic reactivity to decrease, but the nucleophilic reactivity may increase.
In terms of environmental conditions, temperature, pH, light, and the presence or absence of catalysts can all affect its stability. At high temperatures, the thermal motion of molecules intensifies, or the vibration of chemical bonds increases. When the energy reaches a certain level, the chemical bonds may break, and the stability is damaged. In a strong acid and alkali environment, it may change its structure due to protonation or deprotonation, and the stability is also affected. Light or luminescent chemical reactions cause chemical bonds to crack or rearrange, which affects the stability. If there is a suitable catalyst, it may also catalyze its reaction, reducing the stability.
If properly stored, placed in a low temperature, dark, neutral or near neutral environment, and avoid contact with active reagents, this compound may maintain a certain stability. However, once the environment changes, or under specific reaction conditions, it may exhibit reactivity, and various reactions occur, the stability will change accordingly.

1-%28p-tolylsulfonyl%29-2%2C5-dihydropyrrole is an organic compound, but its market price varies due to a variety of factors, making it difficult to determine the value.
First, the quality has a great impact on the price. High purity, less impurities, good reaction effect, large demand in scientific research and high-end production fields, and the price is high; low purity, containing more impurities, or affecting the use, the price is low.
Second, the purchase quantity also affects the price. When purchasing in large quantities, suppliers may give discounts due to economies of scale, and the unit price is reduced; when purchasing in small quantities, the unit price is often high due to relatively high transaction costs.
Third, the market supply and demand relationship plays a significant role. If the demand for this compound is strong and the supply is tight, the price will rise; if the demand is small and the supply is large, the price will easily fall.
Fourth, different suppliers have different pricing strategies. Those with strong strength, excellent cost control, and wide channels may have competitive prices; those who are new to the market or have high operating costs may have slightly higher prices.
Usually in the chemical raw material market, the price fluctuates greatly. In the scientific research reagent market, the price of small-packaged high-purity products may be high; in the large-scale chemical production raw material market, the price may change significantly due to different batches. If you want to know the exact price, you can consult chemical product suppliers, traders, or check the quotation of professional chemical product trading platforms to obtain accurate price information.
