Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, new energy materials, nano-ceramics, nano-hybrid composite materials, preparation and modification of special coatings, In an article, 119139-23-0, name is 3,4-Di(1H-indol-3-yl)-1H-pyrrole-2,5-dione, introducing its new discovery. COA of Formula: C20H13N3O2
A synthetic pathway for the synthesis of unit-B of cryptophycin-24 has been developed using Sharpless asymmetric dihydroxylation as the key step. This study shows that direct azidation of alpha-hydroxy acid ester using diphenylphosphoryl azide is beneficial to asymmetric synthesis of alpha-amino acid without the loss of chirality during the transformation.
Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amountCOA of Formula: C20H13N3O2, you can also check out more blogs about119139-23-0
