The occurrence of 4H,5H,6H,7H,8H-thieno[3,2-b]azepine hydrochloride is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4H,5H,6H,7H,8H-thieno[3,2-b]azepine hydrochloride (CAS 1803591-40-3), molecular formula C8H11NSHCl and molecular weight 189.70 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H11NSHCl, 4H,5H,6H,7H,8H-thieno[3,2-b]azepine hydrochloride contains a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 189.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 4H,5H,6H,7H,8H-thieno[3,2-b]azepine hydrochloride 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.
