n-((5-Chlorothiophen-2-yl)methyl)-n,3-dimethylbut-2-enamide CAS 1258649-26-1 chemical structure

Description

The occurrence of n-((5-Chlorothiophen-2-yl)methyl)-n,3-dimethylbut-2-enamide 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.

CATO supplies n-((5-Chlorothiophen-2-yl)methyl)-n,3-dimethylbut-2-enamide (CAS 1258649-26-1), a certified reference material (molecular formula C11H14ClNOS, MW 243.75 g/mol) for analytical method development and quality control.

Structurally, n-((5-Chlorothiophen-2-yl)methyl)-n,3-dimethylbut-2-enamide (C11H14ClNOS) 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 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 243.75 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 n-((5-Chlorothiophen-2-yl)methyl)-n,3-dimethylbut-2-enamide 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.
