Compared with other compounds in its class, the molecular weight of 218.11 g/mol gives 2-Bromo-5,6-dihydro-4H-cyclopenta[b]thiophen-3-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-5,6-dihydro-4H-cyclopenta[b]thiophen-3-amine (CAS 1602158-73-5) is a high-purity analytical reference standard with the molecular formula C7H8BrNS and a molecular weight of 218.11 g/mol.
Owing to a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system, 2-Bromo-5,6-dihydro-4H-cyclopenta[b]thiophen-3-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.11 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-5,6-dihydro-4H-cyclopenta[b]thiophen-3-amine 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.
