Chemical Structure
Description
2-Bromo-4-(3-(pyridin-2-yl)-1-trityl-1H-pyrazol-4-yl)pyridine (CAS 446880-83-7), molecular formula C32H23BrN4 and molecular weight 543.46 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-4-(3-(pyridin-2-yl)-1-trityl-1H-pyrazol-4-yl)pyridine (C32H23BrN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
