Chemical Structure
Description
5,6,7,8-Tetrahydro-4H-thieno[2,3-c]azepine (CAS 153024-86-3), molecular formula C8H11NSHCl and molecular weight 189.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5,6,7,8-Tetrahydro-4H-thieno[2,3-c]azepine (C8H11NSHCl) is characterized by a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5,6,7,8-Tetrahydro-4H-thieno[2,3-c]azepine 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.
