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 Method development and validation study for quantitative determination of genotoxic impurity and its precursor in fluconazole sample by liquid chromatography-tandem mass spectrometry, published in 2016, which mentions a compound: 86404-63-9, mainly applied to fluconazole liquid chromatog tandem mass spectrometry, Electric Literature of C10H7F2N3O.
Objective: The objective of this work is method development and validation study for quant. determination of 1-[2-(2,4-difluorophenyl)-2,3-epoxypropyl]-1H-1,2,4-triazole, a genotoxic impurity and its precursor in a fluconazole drug sample by liquid chromatog.-tandem mass spectrometry. Methods: LC-MS/MS anal. of these impurities was performed on Hypersil BDS C18 (100 mm x 4.0 mm, 3 μm) column. 5 mmol ammonium acetate and acetonitrile in the ratio of 65:35 (volume/volume) was used as the mobile phase with a flow rate of 0.4 mL/min. The developed method was accomplished with a short run time of 10 min. Triple quadrupole mass detector coupled with pos. electrospray ionization was used for the quantification of genotoxic impurities in multiple reaction monitoring (MRM). Results: The method was validated as per International Conference on Harmonization (ICH) guidelines. The method was linear in the range of 0.30 μg/g to 11.37 μg/g for impurity A and 0.30 μg/g to 11.34 μg/g for impurity B with a correlation coefficient of 0.999. The accuracy of the method was in the range of 98.25 % to 100.53 % for both impurities. Conclusion: A specific, selective, highly sensitive and more accurate anal. method using LC-MS/MS coupled with pos. electrospray ionization has been developed for the quantification of genotoxic impurity (1-[2-(2,4-difluorophenyl)-2,3-epoxypropyl]-1H-1,2,4-triazole) and its precursor (1-(2,4-difluorophenyl)-2-[1,2,4]triazol-1-yl-ethanone) at 0.3 μg/g with respect to the 5.0 mg/mL of fluconazole.
I hope my short article helps more people learn about this compound(1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone)Electric Literature of C10H7F2N3O. Apart from the compound(86404-63-9), you can read my other articles to know other related compounds.
