  2. IUPAC numerical multiplier - Wikipedia

    en.wikipedia.org/wiki/IUPAC_numerical_multiplier

    The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').

  3. 1,8-Bis (dimethylamino)naphthalene - Wikipedia

    en.wikipedia.org/wiki/1,8-Bis(dimethylamino...

    With a pK a of 12.34 [4] for its conjugate acid in aqueous solution, 1,8-bis(dimethylamino)naphthalene is one of the strongest organic bases. However, it only absorbs protons slowly—hence the trade name. The high basicity is attributed to the relief of strain upon protonation and/or the strong interaction between the nitrogen lone pairs.

    Bis(trimethylsilyl)amine (also known as hexamethyldisilazane and HMDS) is an organosilicon compound with the molecular formula [(CH 3) 3 Si] 2 NH. The molecule is a derivative of ammonia with trimethylsilyl groups in place of two hydrogen atoms.

  7. Hapticity - Wikipedia

    en.wikipedia.org/wiki/Hapticity

    This reaction is degenerate and, in the jargon of organic chemistry, it is an example of a sigmatropic rearrangement. [citation needed] A related example is Bis(cyclooctatetraene)iron, in which the η 4 - and η 6-C 8 H 8 rings interconvert. Case 2, typically: complexes containing cyclic polyhapto ligands with maximized hapticity. Such ligands ...

  8. Bisulfite sequencing - Wikipedia

    en.wikipedia.org/wiki/Bisulfite_sequencing

    Gene-set analysis (for example using tools like DAVID and GoSeq) has been shown to be severely biased when applied to high-throughput methylation data (e.g. genome-wide bisulfite sequencing); it has been suggested that this can be corrected using sample label permutations or using a statistical model to control for differences in the numberes ...

    en.wikipedia.org/wiki/Disiamylborane

    Disiamylborane (bis(1,2-dimethylpropyl)borane) is an organoborane with the formula [((CH 3) 2 CHCH(CH 3)) 2 BH] 2 (abbreviation: Sia 2 BH). It is a colorless waxy solid that is used in organic synthesis for hydroboration–oxidation reactions. Like most dialkyl boron hydrides, it has a dimeric structure with bridging hydrides.
