    clc 5 h 4 chcl 2 + h 2 o → clc 5 h 4 cho + 2 hcl It can also be produced by the oxidation of 4-chlorobenzyl alcohol . [ 3 ] [ 4 ] It can be further oxidized to 4-chlorobenzoic acid . [ 5 ]

  3. Benzyl chloride - Wikipedia

    en.wikipedia.org/wiki/Benzyl_chloride

    The reaction proceeds by the free radical process, involving the intermediacy of free chlorine atoms. [4] Side products of the reaction include benzal chloride and benzotrichloride. Other methods of production exist, such as the Blanc chloromethylation of benzene. Benzyl chloride was first prepared from treatment of benzyl alcohol with ...

  4. Mass spectral interpretation - Wikipedia

    en.wikipedia.org/wiki/Mass_spectral_interpretation

    [1] [2] Mass spectra is a plot of relative abundance against mass-to-charge ratio. It is commonly used for the identification of organic compounds from electron ionization mass spectrometry. [3] [4] Organic chemists obtain mass spectra of chemical compounds as part of structure elucidation and the analysis is part of many organic chemistry ...

  5. Selected reaction monitoring - Wikipedia

    en.wikipedia.org/wiki/Selected_reaction_monitoring

    The ion is selected in the second mass spectrometry stage MS2 then undergoes further fragmentation to form ion D + which is selected in the third mass spectrometry stage MS3 and detected. Multiple reaction monitoring ( MRM ) is the application of selected reaction monitoring to multiple product ions from one or more precursor ions, [ 3 ] [ 4 ...

  6. 2,4-Dichlorobenzyl alcohol - Wikipedia

    en.wikipedia.org/wiki/2,4-Dichlorobenzyl_alcohol

    A low-pH throat lozenge containing dichlorobenzyl alcohol (1.2 mg) and amylmetacresol (0.6 mg) has been found to deactivate respiratory syncytial virus and SARS-Cov, but not adenovirus or rhinovirus. [2] A dentifrice containing 10% sodium benzoate and 0.3% dichlorobenzyl alcohol maintains antimicrobial activity for 5 to 10 minutes after ...

  7. 3-Nitrobenzyl alcohol - Wikipedia

    en.wikipedia.org/wiki/3-nitrobenzyl_alcohol

    In mass spectrometry this compound is often abbreviated as "3-NBA" or "m-NBA." It has been used as a liquid matrix for fast atom bombardment [1] and matrix-assisted laser desorption ionization. [2] [3] In electrospray ionization 3-NBA is doped into low surface tension spray solvents to increase analyte charging. [4]

  8. Data-independent acquisition - Wikipedia

    en.wikipedia.org/wiki/Data-independent_acquisition

    Data analysis is generally challenging for DIA methods as the resulting fragment ion spectra are highly multiplexed. In DIA spectra therefore the direct relation between a precursor ion and its fragment ions is lost since the fragment ions in DIA spectra may potentially result from multiple precursor ions (any precursor ion present in the m/z range from which the DIA spectrum was derived).
