1-(2-Bromoethyl)imidazolidin-2-one CAS 328569-74-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Bromoethyl)imidazolidin-2-one.

1-(2-Bromoethyl)imidazolidin-2-one (CAS 328569-74-0), molecular formula C5H9BrN2O and molecular weight 193.04 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(2-Bromoethyl)imidazolidin-2-one (C5H9BrN2O) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 193.04 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
