Reference of 2403-89-6, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 2403-89-6, Name is 1,2,2,6,6-Pentamethylpiperidin-4-ol,introducing its new discovery.
Compounds useful as a stabilizer for a variety of organic materials of an intermediate thereof, or as an intermediate of medicines or agricultural chemicals are disclosed, which are cyclohexylamine derivatives represented by the general formula [I]: STR1 wherein R1 represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an acyl group having 2 to 7 carbon atoms or an arylalkyl group having 7 to 10 carbon atoms; R2 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R3 and R4 both represent a hydrogen atom, or one of R3 and R4 represents a hydrogen atom and the other represents a group –CH2 –R5, or R3 and R4 together form a group =CH–R5, in which R5 represents an unsubstituted or C1 -C4 alkyl substituted phenyl group, a 2-furyl group, a cyclohexyl group or a 2-tetrahydrofuryl group; X represents an alkylene group having 1 to 3 carbon atoms; and n denotes 1 or 2. When the compound is used as a stabilizer, it exhibits little bleedout and high photostabilizing effect.
