  2. Palladium (II) chloride - Wikipedia

    en.wikipedia.org/wiki/Palladium(II)_chloride

    Palladium(II) chloride, also known as palladium dichloride and palladous chloride, are the chemical compounds with the formula PdCl 2.PdCl 2 is a common starting material in palladium chemistry – palladium-based catalysts are of particular value in organic synthesis.

  3. Mass spectral interpretation - Wikipedia

    en.wikipedia.org/wiki/Mass_spectral_interpretation

    In the spectrum for toluene for example, the molecular ion peak is located at 92 m/z corresponding to its molecular mass. Molecular ion peaks are also often preceded by an M-1 or M-2 peak resulting from loss of a hydrogen radical or dihydrogen, respectively. Here, M refers to the molecular mass of the compound.

  4. Mass spectrum - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrum

    A mass spectrum is a histogram plot of intensity vs. mass-to-charge ratio (m/z) in a chemical sample, [1] usually acquired using an instrument called a mass spectrometer. Not all mass spectra of a given substance are the same; for example, some mass spectrometers break the analyte molecules into fragments ; others observe the intact molecular ...

  5. Mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrometry

    Ion mobility spectrometry-mass spectrometry (IMS/MS or IMMS) is a technique where ions are first separated by drift time through some neutral gas under an applied electrical potential gradient before being introduced into a mass spectrometer. [43] Drift time is a measure of the collisional cross section relative to the charge of the ion.

    en.wikipedia.org/wiki/Mass_(mass_spectrometry)

    In mass spectrometry the mass defect is defined as the difference between the exact mass and the nearest integer mass. [21] [22] The Kendrick mass defect is the exact Kendrick mass subtracted from the nearest integer Kendrick mass. [23] Mass defect filtering can be used to selectively detect compounds with a mass spectrometer based on their ...

  7. Bis(triphenylphosphine)palladium chloride - Wikipedia

    en.wikipedia.org/wiki/Bis(triphenylphosphine...

    Bis(triphenylphosphine)palladium chloride is a coordination compound of palladium containing two triphenylphosphine and two chloride ligands. It is a yellow solid that is soluble in some organic solvents. It is used for palladium-catalyzed coupling reactions, e.g. the Sonogashira–Hagihara reaction. The complex is square planar. Many analogous ...

  8. Cobalt(II) chloride - Wikipedia

    en.wikipedia.org/wiki/Cobalt(II)_chloride

    Cobalt(II) chloride is an inorganic compound, a salt of cobalt and chlorine, with the formula CoCl 2. The compound forms several hydrates CoCl 2 ·n H 2 O, for n = 1, 2, 6, and 9. Claims of the formation of tri- and tetrahydrates have not been confirmed. [4] The anhydrous form is a blue crystalline solid; the dihydrate is purple and the ...

  9. Dichlorobis(ethylenediamine)nickel(II) - Wikipedia

    en.wikipedia.org/wiki/Dichlorobis(ethylenedi...

    Dichlorobis(ethylenediamine)nickel(II) is the inorganic compound with the formula NiCl 2 (en) 2, where en = ethylenediamine. The formula is deceptive: the compound is the chloride salt of the coordination complex [Ni 2 Cl 2 (en) 4] 2+. This blue solid is soluble in water and some polar organic solvents.
