Metribuzin (4-amino-6-tert-butyl-3-(methylthio)-1,2,4-triazin-5(4H)-one) is a herbicide used both pre- and post-emergence in crops including soy bean, potatoes, tomatoes and sugar cane. It acts by inhibiting photosynthesis by disrupting photosystem II. [2] It is widely used in agriculture and has been found to contaminate groundwater. [3]
Tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate is a chemical compound used as a polymer stabilizer in plastics. Like other hindered phenols it acts as a primary antioxidant. More than 1000 tonnes per year are used in the EU.
The effect of the tert-butyl group on the progress of a chemical reaction is called the Thorpe–Ingold effect illustrated in the Diels-Alder reaction below. Compared to a hydrogen substituent, the tert-butyl substituent accelerates the reaction rate by a factor of 240. [2] tert-Butyl effect. The tert-butyl effect is an example of steric hindrance.
705 mg mL −1: Melting point: −122 to −120 °C; −188 to −184 °F; 151 to 153 K Boiling point: ... 3-Methylheptane is a branched alkane isomeric to octane.
2,2,4,4-Tetramethyl-3-t-butyl-pentane-3-ol or tri-tert-butylcarbinol is an organic compound with formula C 13 H 28 O, ((H 3 C) 3 C) 3 COH, or t Bu 3 COH. [1] It is an alcohol that can be viewed as a structural analog of a tridecane isomer ( 2,2,4,4-tetramethyl-3- t -butylpentane ) where the central hydrogen has been replaced by a hydroxyl group ...
4-tert-Butylphenol is an organic compound with the formula (CH 3) 3 CC 6 H 4 OH. It is one of three isomeric tert-butyl phenols. It is a white solid with a distinct phenolic odor. It dissolves in basic water. [2]
