Tetramethylsilane (abbreviated as TMS) is the organosilicon compound with the formula Si (CH 3) 4. It is the simplest tetraorganosilane. Like all silanes, the TMS framework is tetrahedral. TMS is a building block in organometallic chemistry but also finds use in diverse niche applications.
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 many 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 ...
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as a structural analog of a tridecane isomer ( 2,2,4,4-tetramethyl-3- t -butylpentane ) where the central hydrogen has been replaced by a hydroxyl group ...
Tetramethylammonium hydroxide ( TMAH or TMAOH) is a quaternary ammonium salt with molecular formula N (CH 3) 4+ OH −. It is commonly encountered in form of concentrated solutions in water or methanol. TMAH in solid state and its aqueous solutions are all colorless, but may be yellowish if impure.
Infobox references. 2,2,4,4-Tetramethyl-1,3-cyclobutanediol (CBDO) is an aliphatic diol. This diol is produced as a mixture of cis - and trans - isomers, depending on the relative stereochemistry of the hydroxyl groups. It is used as a monomer for the synthesis of polymeric materials, usually as an alternative to bisphenol A (BPA).
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 2,2,4,4-Tetramethylcyclobutanedione is the organic compound with the formula (CH 3) 4 C 4 O 2. The compound is a diketone of cyclobutane, bearing four methyl groups. It is a white solid that is used as a precursor to diverse ...
4,4′-Methylenedianiline (MDA) is an organic compound with the formula CH 2 (C 6 H 4 NH 2) 2. It is a colorless solid, although commercial samples can appear yellow or brown. It is a colorless solid, although commercial samples can appear yellow or brown.
