Chemical Structure
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-ethyl-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxamide.
2-Amino-N-ethyl-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxamide (CAS 301321-98-2), molecular formula C12H18N2OS and molecular weight 238.35 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Amino-N-ethyl-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxamide (C12H18N2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 238.35 g/mol, it falls into the medium-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.
CATO manufactures 2-Amino-N-ethyl-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
