Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
{4-amino-5-bromo-7-methylpyrrolo[2,1-f][1,2,4]triazin-6-yl}methanol (CAS 1443532-11-3) is a high-purity analytical reference standard with the molecular formula C8H17BrN4O and a molecular weight of 265.15 g/mol.
The molecular framework of {4-amino-5-bromo-7-methylpyrrolo[2,1-f][1,2,4]triazin-6-yl}methanol (C8H17BrN4O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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.
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.
