Chemical Structure
Description
As a certified reference material (CRM), (4-Bromobutyl)(3,4-dichlorophenyl)sulfane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
(4-Bromobutyl)(3,4-dichlorophenyl)sulfane (CAS 77248-74-9), molecular formula C10H11BrCl2S and molecular weight 314.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-Bromobutyl)(3,4-dichlorophenyl)sulfane (C10H11BrCl2S) is characterized by sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
