| | 4,4'-メチレンビス(2,6-ジ-tert-ブチルフェノール) Usage And Synthesis |
| 外観 | 白色～黄赤色～緑色粉末～結晶 | | 説明 | bis-BHT (118-82-1) is a potent antioxidant. Cell permeable. | | 化学的特性 | light yellow crystalline | | 使用 | Antioxidant. | | 定義 | ChEBI: 4,4'-Methylenebis(2,6-di-tert-butylphenol) is a diarylmethane. | | 主な応用 | 4,4'-Methylenebis(2,6-di-tert-butylphenol), also known as H2-4DBP, could be used as a ligand to react with sets of M(OR)x and MRx. The ligand possesses more flexibility than OBzP or catecholate derivatives, and the para-OH makes it of interest for controlled alcoholysis. This compound has several characteristics, including (i) the ortho position possesses the sterically hindering t-butyl group which will assist in minimizing oligomerization, (ii) the para linkage prevents chelation of the 4DBP ligand to the metal upon coordination, and (iii) may act as a valuable model for complexation behavior of the plastic precursor bisphenol-A [BPA; 4,4' -(propane-2,2-diyl)diphenol] that has become of recent concern[2].
