Chemical Structure
Description
CATO supplies 6-Bromo-4-(piperazin-1-yl)quinazoline (CAS 205259-86-5), a certified reference material (molecular formula C12H13BrN4, MW 293.16 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H13BrN4, 6-Bromo-4-(piperazin-1-yl)quinazoline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 293.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
