Compared with other compounds in its class, the molecular weight of 215.07 g/mol gives 5-Bromo-4-mercaptonicotinonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Bromo-4-mercaptonicotinonitrile (CAS 1706465-17-9), a certified reference material (molecular formula C6H3BrN2S, MW 215.07 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H3BrN2S, 5-Bromo-4-mercaptonicotinonitrile contains a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
