Chemical Structure
Description
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.
1-Bromo-3-[(2-chloroethyl)sulfanyl]benzene (CAS 1341412-54-1) is a high-purity analytical reference standard with the molecular formula C8H8BrClS and a molecular weight of 251.57 g/mol.
Owing to sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system, 1-Bromo-3-[(2-chloroethyl)sulfanyl]benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 251.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
