Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Amino-N-(2,4-dichlorophenyl)-6-ethyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide.
2-Amino-N-(2,4-dichlorophenyl)-6-ethyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide (CAS 590351-13-6), molecular formula C17H18Cl2N2OS and molecular weight 369.31 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Amino-N-(2,4-dichlorophenyl)-6-ethyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide (C17H18Cl2N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 369.31 g/mol, it falls into the moderately-high-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), 2-Amino-N-(2,4-dichlorophenyl)-6-ethyl-4,5,6,7-tetrahydro-1-benzothiophene-3-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.
