2-(2H-Benzotriazol-2-yl)-6-[3-(1,1,1,3,5,5,5-heptamethyl-3-trisiloxanyl)-2-methylpropyl]-4-methylphenol(CAS: 155633-54-8)

This compound is a white crystalline solid with a high molecular weight. It has low solubility in water but good solubility in organic solvents. It exhibits good stability and low reactivity under normal conditions. However, it may show some reactivity towards strong acids or bases. Spectroscopic data such as IR, NMR, and MS can be used to confirm its identity.

This compound can be synthesized via a multistep approach involving the protection of a phenol group, introduction of a benzotriazole moiety, followed by trisiloxane and methyl group modifications. Common reagents include benzotriazolyl chlorides, silanes, and methyl halides. Specific conditions such as temperature, solvent, and catalysts (e.g., phosphine ligands) are crucial for achieving high yield and selectivity.

This compound is primarily used in the pharmaceutical industry for its antioxidant and photostabilizing properties. It is also applied in polymer science as a stabilizer and in semiconductor manufacturing for its unique chemical structure. Additionally, it can be employed in sensor technology for its sensitivity to certain chemical environments.

When handling this compound, it is essential to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat due to its potential irritant properties. Use a fume hood to minimize exposure to airborne particles. In case of a spill, neutralize it with an appropriate absorbent material and dispose of it according to local regulations. Always consult the Safety Data Sheet (SDS) for detailed handling and disposal information.
