Description
CATO supplies 6-hydroxy-2-[(thiophen-2-yl)methylidene]-2,3-dihydro-1-benzofuran-3-one 637753-83-4 Z119968726 (CAS 637753-83-4), a certified reference material (molecular formula C13H8O3S, MW 244.27 g/mol) for analytical method development and quality control.
The molecular framework of 6-hydroxy-2-[(thiophen-2-yl)methylidene]-2,3-dihydro-1-benzofuran-3-one 637753-83-4 Z119968726 (C13H8O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 6-hydroxy-2-[(thiophen-2-yl)methylidene]-2,3-dihydro-1-benzofuran-3-one 637753-83-4 Z119968726 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.
