Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-bromo-2-chloropyrrolo[2,1-f][1,2,4]triazine.
5-bromo-2-chloropyrrolo[2,1-f][1,2,4]triazine (CAS 1233143-59-3) is a high-purity analytical reference standard with the molecular formula C6H11BrClN3 and a molecular weight of 240.53 g/mol.
Owing to a nitrile group, chlorine/bromine substitution, 5-bromo-2-chloropyrrolo[2,1-f][1,2,4]triazine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
