Description
CATO supplies 2-Bromo-5-(4-hexylphenyl)thiophene (CAS 934368-79-3), a certified reference material (molecular formula C16H19BrS, MW 323.29 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, bromine substitution, a polycyclic aromatic system, 2-Bromo-5-(4-hexylphenyl)thiophene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.29 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.
As a certified reference material (CRM), 2-Bromo-5-(4-hexylphenyl)thiophene 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.
