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 Syntheses and spectral properties of new dicyanopyrazine-related heterocycles from diaminomaleonitrile, published in 1998, which mentions a compound: 56413-95-7, mainly applied to dicyanopyrazine precursor fluorescent dye synthesis; quinoxaline dye preparation dicyanopyrazine precursor; furopyrazine dye preparation dicyanopyrazine precursor; pyrrolopyrazine dye preparation dicyanopyrazine precursor; pyrazinoporphyrazine dye preparation dicyanopyrazine precursor, Recommanded Product: 56413-95-7.
New dicyanopyrazine-related heterocycles such as quinoxalines, furopyrazines, pyrrolopyrazines, and pyrazinoporphyrazines were synthesized and their absorption and fluorescence spectra were correlated with their structures.
In some applications, this compound(56413-95-7)Recommanded Product: 56413-95-7 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
