Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 141.23 g/mol gives (5-ethylthien-2-yl)methylamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (5-ethylthien-2-yl)methylamine (CAS 104162-80-3), a certified reference material (molecular formula C7H11NS, MW 141.23 g/mol) for analytical method development and quality control.
Structurally, (5-ethylthien-2-yl)methylamine (C7H11NS) contains a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 141.23 g/mol, it falls into the low-molecular-weight range. 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), (5-ethylthien-2-yl)methylamine 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.
