N-[(5Z)-5-{[(3,5-dimethoxyphenyl)amino]methylidene}-6-oxo-4H,5H,6H-cyclopenta[b]thiophen-4-yl]-2,2,2-trifluoroacetamide CAS 865659-11-6

Description

N-[(5Z)-5-{[(3,5-dimethoxyphenyl)amino]methylidene}-6-oxo-4H,5H,6H-cyclopenta[b]thiophen-4-yl]-2,2,2-trifluoroacetamide (CAS 865659-11-6), molecular formula C18H15F3N2O4S and molecular weight 412.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-[(5Z)-5-{[(3,5-dimethoxyphenyl)amino]methylidene}-6-oxo-4H,5H,6H-cyclopenta[b]thiophen-4-yl]-2,2,2-trifluoroacetamide (C18H15F3N2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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 N-[(5Z)-5-{[(3,5-dimethoxyphenyl)amino]methylidene}-6-oxo-4H,5H,6H-cyclopenta[b]thiophen-4-yl]-2,2,2-trifluoroacetamide 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.
