Chemical Structure
Description
The occurrence of 2-Bromo-1-(4-methylpiperazin-1-yl)butan-1-one is closely related to an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-1-(4-methylpiperazin-1-yl)butan-1-one (CAS 1119453-01-8), molecular formula C9H17BrN2O and molecular weight 249.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-1-(4-methylpiperazin-1-yl)butan-1-one (C9H17BrN2O) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
