Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Bromopent-4-en-1-yl)-3-chloro-5-fluorobenzene.
CATO supplies 1-(4-Bromopent-4-en-1-yl)-3-chloro-5-fluorobenzene (CAS 1143461-50-0), a certified reference material (molecular formula C11H11BrClF, MW 277.56 g/mol) for analytical method development and quality control.
Structurally, 1-(4-Bromopent-4-en-1-yl)-3-chloro-5-fluorobenzene (C11H11BrClF) contains fluorine/chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 277.56 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
