4-CARBOXY-2,2,6,6-TETRAMETHYLPIPERIDINE 1-OXYL Usage And Synthesis

Uses

4-Carboxy-TEMPO may be employed as catalyst for the oxidation of regenerated cellulose (viscose rayon) to cellouronic acid. 4-Carboxy-TEMPO is a 4-substituted 2,2,6,6-tetramethylpiperidyl-1-oxy (TEMPO) derivative. 4-carboxy-TEMPO immobilized with 3-aminopropylsilane on the mesoporous silica surface comprises heterogeneous catalytic system employed for various oxidation reactions.

Definition

ChEBI: 4-carboxy-TEMPO is a member of the class of aminoxyls that is TEMPO carrying a carboxy group at position 4. It has a role as a radical scavenger, a MRI contrast agent and a spin label. It is a member of aminoxyls and a piperidinemonocarboxylic acid. It is functionally related to a TEMPO.
