Chemical Structure
Description
The occurrence of 1-[3-Bromo-4-(methylsulfanyl)phenyl]ethan-1-one is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-[3-Bromo-4-(methylsulfanyl)phenyl]ethan-1-one (CAS 79324-78-0), molecular formula C9H9BrOS and molecular weight 245.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 1-[3-Bromo-4-(methylsulfanyl)phenyl]ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 245.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
