(4-isothiocyanato-2,2,6,6-tetramethylpiperidin-1-yl)oxidanyl - Introduction
(4-isothiocyyanato-2, 2,6, phenyl) oxidanyl, also known as ITOX((4-isothiocyyanato-2, 2,6, phenyl) oxidanyl), is an organic free radical compound.
Nature:
1. Appearance: colorless to light yellow solid or liquid;
2. molecular formula: C12H21N3OS;
3. Molecular weight: 259.38;
4. melting point: below 0 ℃;
5. Flash point: not applicable (with low volatility).
Use:
ITOX is often used as an oxidant and free radical initiator. It has a high redox capacity and can be used as a catalyst for oxidation reactions in organic synthesis. In addition, it can be used as a free radical initiator in rubbers, polymers and coatings.
Preparation Method:
ITOX can be synthesized by oxidizing 2,2, 6,6-tetramethyl-4-piperidone to the corresponding oxide in a nitrogen atmosphere. The oxide is then converted to (4-isothiocyanato-2,2,6, r) oxidanyl by reaction with thioisocyanate.
Safety Information:
1. ITOX has strong irritation and may cause damage to the eyes, skin, respiratory system and digestive system, so protective gloves and protective glasses should be worn when using;
2. During the operation, it is necessary to provide good ventilation conditions to avoid inhalation and skin contact;
3. ITOX is a free radical compound and needs to be stored in a cold and dark place, avoiding direct sunlight and high temperature.
Please note that ITOX is an organic compound with high activity. When used, it should follow appropriate safety procedures and operate under appropriate equipment and conditions in the organic synthesis laboratory.
