Chemical Structure
Description
The occurrence of 3-{[(2,6-dichlorophenyl)methyl]sulfanyl}-N-methylthiophene-2-carboxamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-{[(2,6-dichlorophenyl)methyl]sulfanyl}-N-methylthiophene-2-carboxamide (CAS 251097-34-4), molecular formula C13H11Cl2NOS2 and molecular weight 332.27 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-{[(2,6-dichlorophenyl)methyl]sulfanyl}-N-methylthiophene-2-carboxamide (C13H11Cl2NOS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 332.27 g/mol, it falls into the moderately-high-molecular-weight range. 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-{[(2,6-dichlorophenyl)methyl]sulfanyl}-N-methylthiophene-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.
