Safety of 4-Nitrobenzoic acid. I found the field of Chemistry very interesting. Saw the article Metal-free tandem reaction synthesis of spiro-cyclopropyl fused pyrazolin-5-one derivatives published in 2019.0, Reprint Addresses Xu, YJ (corresponding author), Sichuan Normal Univ, Coll Chem & Mat Sci, Chengdu 610066, Sichuan, Peoples R China.; Dong, L (corresponding author), Sichuan Univ, West China Sch Pharm, Educ Minist, Key Lab Drug Targeting & Drug Delivery Syst, Chengdu 610041, Sichuan, Peoples R China.. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid.
A highly efficient cascade annulation approach was developed for the synthesis of novel spiro-cyclopropyl fused pyrazolin-5-ones from pyrazole-3-ketone substrates and two-component sulfur ylides in an acidic environment. This metal-free one-pot reaction has the advantages of easily available active materials, simple operation and brand new spirocyclic skeletons.
Safety of 4-Nitrobenzoic acid. Bye, fridends, I hope you can learn more about C7H5NO4, If you have any questions, you can browse other blog as well. See you lster.
