Chemical Structure
Description
CATO supplies 7-bromopyrrolo[2,1-f][1,2,4]triazine-2-carbonitrile (CAS 2090675-40-2), a certified reference material (molecular formula C7H11BrN4, MW 231.09 g/mol) for analytical method development and quality control.
Structurally, 7-bromopyrrolo[2,1-f][1,2,4]triazine-2-carbonitrile (C7H11BrN4) contains a nitrile group, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 231.09 g/mol, it falls into the medium-molecular-weight range. 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.
