Applications

4-tert-Butylthiophenol is a compound that has various applications in the field of photochemistry and electrochemistry. In a study, it is used in conjunction with visible light to convert quinones to quinols, mimicking the function of quinone pools in photosynthesis. This highlights its potential role in harnessing light energy for chemical reactions. In other study, 4-tert-butylthiophenol is compared to another compound, 1-adamantanethiolate, in the context of electrochemiluminescence (ECL) of metal nanoclusters. The results show that the presence of 4-tert-butylthiophenol weakens the ECL signal of the nanocluster. Additionally, the compound exhibits solid-state ECL emissions at a wavelength of 770 nm, which is blue-shifted compared to its corresponding solid-state photoluminescence emission. These findings demonstrate that the properties and performance of metal nanoclusters can be significantly influenced by the subtle differences in the composition of their core. The use of 4-tert-butylthiophenol and similar compounds in atomically precise emissive metal nanoclusters shows promise for applications in sensing and immunoassay platforms, offering a potential basis for developing advanced diagnostic tools. ^2,3

Safety

4-tert-Butylthiopheno presents safety concerns that should be carefully considered. Structurally similar to tyrosine, it serves as a substrate for tyrosinase, which oxidizes it to form a quinone. This quinone can rapidly react with glutathione and, in the absence of a sufficient GSH defense system, may generate reactive oxygen species that can damage melanocytes, leading to leukoderma/vitiligo. Additionally, it has been found to be irritating to the eyes, nose, and throat, and inhalation can lead to difficulty breathing. In the event of a spill, it is important to use absorbent paper to pick up all liquid material and seal contaminated clothing and absorbent paper in a vapor-tight plastic bag for proper disposal. Contaminated surfaces should be solvent-washed with alcohol followed by a strong soap and water solution. It is crucial not to reenter the contaminated area until it has been verified as properly cleaned by the Safety Officer or another responsible person. Overall, handling 4-tert-butylthiophenol requires strict adherence to safety protocols to prevent exposure and minimize potential health risks. ⁴
