Chemical Structure
Description
The occurrence of 5-Chloro-N-(tetrahydro-2H-pyran-4-yl)-N-(2-(thiophen-2-yl)ethyl)thiophene-2-carboxamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Chloro-N-(tetrahydro-2H-pyran-4-yl)-N-(2-(thiophen-2-yl)ethyl)thiophene-2-carboxamide (CAS 1787916-06-6) is a high-purity analytical reference standard with the molecular formula C16H18ClNO2S2 and a molecular weight of 355.90 g/mol.
The molecular framework of 5-Chloro-N-(tetrahydro-2H-pyran-4-yl)-N-(2-(thiophen-2-yl)ethyl)thiophene-2-carboxamide (C16H18ClNO2S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 5-Chloro-N-(tetrahydro-2H-pyran-4-yl)-N-(2-(thiophen-2-yl)ethyl)thiophene-2-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.
