In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Development, characterisation, and deployment of the SNO+ liquid scintillator, published in 2020, which mentions a compound: 92-71-7, mainly applied to tin oxide liquid scintillator ease of handling, Category: thiazole.
A liquid scintillator consisting of linear alkylbenzene as the solvent and 2,5-diphenyloxazole as the fluor was developed for the SNO+ experiment This mixture was chosen as it is compatible with acrylic and has a competitive light yield to pre-existing liquid scintillators while conferring other advantages including longer attenuation lengths, superior safety characteristics, chem. simplicity, ease of handling, and logistical availability. Its properties have been extensively characterized and are presented here. This liquid scintillator is now used in several neutrino physics experiments in addition to SNO+.
In addition to the literature in the link below, there is a lot of literature about this compound(2,5-Diphenyloxazole)Category: thiazole, illustrating the importance and wide applicability of this compound(92-71-7).
