Tom ntej: 2,2,6,6-Tetramethyl-4-piperidinol CAS 2403-88-5
2,2,6,6-Tetramethyl-4-piperidinol yog dawb crystalline hmoov nyob rau hauv chav tsev kub, soluble nyob rau hauv organic solvents xws li acetone, ethanol, thiab chloroform, me ntsis soluble nyob rau hauv dej, thiab muaj hygroscopicity. Nws kuj muaj photostability thiab muaj cov ntawv thov tseem ceeb hauv cov tshuaj. Hindered amine lub teeb stabilizers tam sim no yog cov khoom siv zoo tshaj plaws polymer lub teeb stabilizers, thiab yog ib chav kawm ntawm cov organic amine compounds nrog steric hindrance teebmeem.
