Chemical Structure
Description
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 supplies Methyl 3-[(E)-[(dimethylamino)methylidene]amino]-4-(3-fluorophenyl)thiophene-2-carboxylate (CAS 1785932-85-5), a certified reference material (molecular formula C15H15FN2O2S, MW 306.36 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3-[(E)-[(dimethylamino)methylidene]amino]-4-(3-fluorophenyl)thiophene-2-carboxylate (C15H15FN2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures Methyl 3-[(E)-[(dimethylamino)methylidene]amino]-4-(3-fluorophenyl)thiophene-2-carboxylate 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.
