Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 259.21 g/mol gives 1-Bromo-4-[(3-methylbutyl)thio]benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Bromo-4-[(3-methylbutyl)thio]benzene (CAS 76542-20-6) is a high-purity analytical reference standard with the molecular formula C11H15BrS and a molecular weight of 259.21 g/mol.
1-Bromo-4-[(3-methylbutyl)thio]benzene (C11H15BrS) contains sulfur-containing functionality, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 1-Bromo-4-[(3-methylbutyl)thio]benzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
