Chemical Structure
Description
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.
1-{7-bromopyrrolo[2,1-f][1,2,4]triazin-2-yl}ethan-1-one (CAS 1369138-52-2), molecular formula C8H14BrN3O and molecular weight 248.12 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-{7-bromopyrrolo[2,1-f][1,2,4]triazin-2-yl}ethan-1-one (C8H14BrN3O) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 248.12 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
