5-bromothiophen-3-amine CAS 81974-99-4

Description

Compared with other compounds in its class, the molecular weight of 182.08 g/mol gives 5-bromothiophen-3-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-bromothiophen-3-amine (CAS 81974-99-4) is a high-purity analytical reference standard with the molecular formula C4H8BrNS and a molecular weight of 182.08 g/mol.

Owing to sulfur-containing functionality, bromine substitution, 5-bromothiophen-3-amine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.08 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), 5-bromothiophen-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.
