Chemical Structure

2-Bromo-3-(2-butyloctyl)thiophene CAS 1908409-36-8 chemical structure

Description

2-Bromo-3-(2-butyloctyl)thiophene (CAS 1908409-36-8) is a high-purity analytical reference standard with the molecular formula C16H27BrS and a molecular weight of 331.35 g/mol.

Owing to sulfur-containing functionality, bromine substitution, 2-Bromo-3-(2-butyloctyl)thiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 331.35 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).

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-3-(2-butyloctyl)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.
