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, 126456-43-7, name is (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol, introducing its new discovery. SDS of cas: 126456-43-7
A compound of formula (I), wherein R1 is alkyl, alkenyl, cycloalkyl, cycloalkenyl, heterocycloalkyl, heterocycloalkenyl, aryl, heteroaryl, heteropolycyclyl or polycyclyl, any of which is optionally substituted with alkyl, heteroaryl, aryl or -O-aryl; R2 is alkyl, alkenyl or aryl, any of which is optionally substituted with hydroxy, halogen, aryl, heteroaryl, cycloalkyl, cycloalkenyl, -C(O)NH-aryl, heterocycloalkyl, heterocycloalkenyl, heteropolycyclyl or polycyclyl; R3 is hydrogen or aryl; R4is alkyl, alkenyl, alkoxy, alkylthio or aryl, any of which is optionally substituted with hydroxy, aryl, heteroaryl, cycloalkyl, cycloalkenyl, thioalkyl, heterocycloalkyl, heterocycloalkenyl, heteropolycyclyl or polycyclyl; R5 is hydrogen or an alkyl or alkenyl group optionally substituted with hydroxy, aryl, -C(O)O- alkyl or -C(O)NH- alkyl; or R4-C-R5 taken together form cycloalkyl, cycloalkenyl or polycyclyl, any of which is optionally substituted with alkyl or hydroxyalkyl; R6 is hydrogen, alkyl, -alkyl-aryl or -alkyl-heteroaryl; or a pharmaceutically-acceptable salt thereof.
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. SDS of cas: 126456-43-7, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 126456-43-7, in my other articles.
