Chemical Structure
Description
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, 1-(5-Bromothiophen-2-yl)ethanol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
1-(5-Bromothiophen-2-yl)ethanol (CAS 34878-41-6), molecular formula C6H7BrOS and molecular weight 207.09 g/mol, is a CATO reference standard with documented purity and traceability.
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), 1-(5-Bromothiophen-2-yl)ethanol 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.
