Chemical Structure
Description
The occurrence of 4-(2-Bromoethyl)-3-ethylpiperidine is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(2-Bromoethyl)-3-ethylpiperidine (CAS 808100-55-2), molecular formula C9H18BrN and molecular weight 220.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(2-Bromoethyl)-3-ethylpiperidine (C9H18BrN) is characterized by 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.
