Chemical Structure
Description
The molecular framework of 5-bromo-2,4-dichloro-pyrrolo[2,1-f][1,2,4]triazine (C6H10BrCl2N3) is characterized by a nitrile group, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
5-bromo-2,4-dichloro-pyrrolo[2,1-f][1,2,4]triazine (CAS 2216746-83-5), molecular formula C6H10BrCl2N3 and molecular weight 274.97 g/mol, is a CATO reference standard with documented purity and traceability.
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.
