Chemical Structure
Description
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.
7-Bromo-2-cyclopropylpyrrolo[2,1-f][1,2,4]triazine (CAS 1369138-91-9) is a high-purity analytical reference standard with the molecular formula C9H8BrN3 and a molecular weight of 238.08 g/mol.
7-Bromo-2-cyclopropylpyrrolo[2,1-f][1,2,4]triazine (C9H8BrN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
