Chemical Structure
Description
CATO supplies 4-Bromo-1-[Tris(Propan-2-Yl)Silyl]-1h-Pyrrolo[2,3-B]Pyridine (CAS 934388-23-5), a certified reference material (molecular formula C10H13BrN2Si, MW 269.21 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H13BrN2Si, 4-Bromo-1-[Tris(Propan-2-Yl)Silyl]-1h-Pyrrolo[2,3-B]Pyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 269.21 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).
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.
