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 tert-Butyl 4-(2-bromoacetyl)piperazine-1-carboxylate.
CATO supplies tert-Butyl 4-(2-bromoacetyl)piperazine-1-carboxylate (CAS 112257-12-2), a certified reference material (molecular formula C11H19BrN2O3, MW 307.18 g/mol) for analytical method development and quality control.
The molecular framework of tert-Butyl 4-(2-bromoacetyl)piperazine-1-carboxylate (C11H19BrN2O3) is characterized by an amide group, a carboxylic acid 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.
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.
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.
