Chemical Structure
Description
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.
1-[(2-bromoethyl)sulfanyl]-4-chlorobenzene (CAS 13290-31-8), molecular formula C8H8BrClS and molecular weight 251.57 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-[(2-bromoethyl)sulfanyl]-4-chlorobenzene (C8H8BrClS) is characterized by sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
