Shows the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) to 3,3',5,5'-tetramethylbenzidine diimine. The resulting one-electron oxidation product is a diimine-diamine complex, which causes the solution to take on a blue colour, [2] and this colour change can be read on a spectrophotometer at the wavelengths of 370 and 650 nm.
Tetramethylbutane, sometimes called hexamethylethane, is a hydrocarbon with formula C 8 H 18 or (H 3 C-) 3 C-C(-CH 3) 3. It is the most heavily branched and most compact of the octane isomers, the only one with a butane (C4) backbone. Because of its highly symmetrical structure, it has a very high melting point and a short liquid range; in fact ...
A series of articles describes it: Peak Integration Part 1, [2] Peak Integration Part 2, [3] Peak Integration Part 3. [4] The parameters inside the chromatography software which affect the integration are called the Integration events. [5]
Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate) is a chemical compound composed of four sterically hindered phenols linked through a pentaerythritol core. It is used as primary antioxidant for stabilizing polymers, particularly polyethylene and polypropylene.
1,3,5,7-Tetramethyl-1,3,5,7-tetrasilaadamantane is the organosilicon compound with the formula (CH 2) 6 (SiCH 3) 4. It is a colorless solid that is soluble in organic solvents. The compound is one of the iconic carbosilanes, featuring alternating −Si−C−Si−C− linkages. [2] Otherwise it can be described as a diamondoid cluster.
Multisim includes microcontroller simulation (formerly known as MultiMCU), [3] as well as integrated import and export features to the printed circuit board layout software in the suite, NI Ultiboard. [4] Multisim is widely used in academia and industry for circuits education, electronic schematic design and SPICE simulation. [5]

Trithioacetone was first made in 1889 by Baumann and Fromm, by reaction of hydrogen sulfide with acetone. [6] In the presence of an acidified ZnCl 2 catalyst at 25 °C, one obtains a product that is 60–70% trithioacetone, 30–40% of 2,2-propanedithiol, and small amounts of two isomeric impurities, 3,3,5,5,6,6-hexamethyl-1,2,4-trithiane and 4-mercapto-2,2,4,6,6-pentamethyl-1,3-dithiane.
