Chemical Structure
Description
3-Amino-N-[(4-chlorophenyl)methyl]-4,6-dimethylthieno[2,3-β]pyridine-2-carboxamide (CAS 633283-39-3) is a high-purity analytical reference standard with the molecular formula C17H16ClN3OS and a molecular weight of 345.85 g/mol.
Based on its molecular formula C17H16ClN3OS, 3-Amino-N-[(4-chlorophenyl)methyl]-4,6-dimethylthieno[2,3-β]pyridine-2-carboxamide contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 345.85 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 3-Amino-N-[(4-chlorophenyl)methyl]-4,6-dimethylthieno[2,3-β]pyridine-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.
