The compound is one of P-aminophenol Buy three isomeric aminophenols, the other two being 2-aminophenol and 3-aminophenol.
4-Aminophenol is a building block used in organic chemistry. Prominently, P-aminophenol Hydrochloride is the final intermediate in the industrial synthesis of Paracetamol . Treating 4-aminophenol with acetic anhydride gives paracetamol.

[ China Agricultural Machinery Industry News ] The nine-year temporary corn storage policy has withdrawn from the historical stage in 2016, which is interpreted as a breakthrough in China's agricultural supply-side reform. In Heilongjiang, a province with large grain production, “market-based acquisition†and “subsidy†have become the “new order†for corn circulation, which has brought pain to the local corn industry.
In the face of pain, Heilongjiang Province actively explored the adjustment of planting structure and accelerated the independent development of corn processing enterprises. The No. 1 Document of the Central Committee released this year proposes that deepening the price formation mechanism and the reform of the storage system of important agricultural products such as grain and optimizing the industrial structure of products will point the way to local agriculture in the midst of pain.
"Market-based acquisition + subsidy" into a new order of corn circulation
In the past year, corn prices have fallen sharply, which is a test for Han Xiaoyan, a farmer in Dawn Town, Zhaodong City, Heilongjiang Province.
Han Xiaoyan: Now we are expanding the area to plant some potential vegetables, okra, naked pumpkin, organic corn, and have always pursued high yields. Now we have to pursue quality.
Over the years, the state has purchased the protection price, and many farmers only pay attention to the quality of production. The corn market has gone from “policy market†to “market marketâ€, and the low quality naturally sells at a price. This made the local farmers soberly aware that the days of "selling the grain while sitting on the hoe" are gone forever.
The abolition of the corn storage policy accelerated the independent development of production enterprises while guiding farmers to actively adjust the planting structure. Liu Naiqing, head of the Grain Pure Organic Weeds Co., Ltd. of Jiamusi City, Heilongjiang Province, told the reporter that the company has built a factory for five years to rely on its own organic brand. The products are not only expensive but also in short supply.
Liu Naiqing: I have planted 300 mu of land this year. I have not sold enough. The price of other corn is low. We are high. The market needs real healthy and safe food that is good for the human body and caters to the market.
The positive effects of reform are emerging. According to the Central Agricultural Office, the current domestic corn price is lower than the foreign import tariffs, and domestic corn has international competitiveness. This year's Central Document No. 1 proposed to deepen the reform of the price formation mechanism and the storage system of important agricultural products such as grain. This provides a direction for Heilongjiang agriculture that has developed in the pain.
Li Shirun, deputy director of the Agricultural Committee of Heilongjiang Province, said: The adjustment is also gradual. The overall goal is to adjust the quality of agricultural products, increase the industry, raise the standard, and adjust the benefits.
