Chemical Structure
Description
Owing to sulfur-containing functionality, bromine substitution, 2-Bromo-5-(2-ethylhexyl)thiophene is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 275.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 2-Bromo-5-(2-ethylhexyl)thiophene (CAS 925899-21-4), a certified reference material (molecular formula C12H19BrS, MW 275.25 g/mol) for analytical method development and quality control.
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-(2-ethylhexyl)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.
