Chemical Structure
Description
As a certified reference material (CRM), 3-Amino-N-(3,4-dimethylphenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide 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.
3-Amino-N-(3,4-dimethylphenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide (CAS 625370-16-3), molecular formula C22H25N3OS and molecular weight 379.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Amino-N-(3,4-dimethylphenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide (C22H25N3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
