Chemical Structure
Description
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.
2-(Methylthio)-1-phenyl-1H-[1,2,4]triazolo[1,5-c]quinazolin-4-ium iodide (CAS 62495-55-0), molecular formula C16H13N4SI and molecular weight 420.27 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H13N4SI, 2-(Methylthio)-1-phenyl-1H-[1,2,4]triazolo[1,5-c]quinazolin-4-ium iodide contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 420.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
