Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 40682-97-1 4H-1-Benzopyran-3-carboxaldehyde, 7-methyl-4-oxo- CTK1D4361 (CAS 40682-97-1), a certified reference material (molecular formula C11H8O3, MW 188.18 g/mol) for analytical method development and quality control.
The molecular framework of 40682-97-1 4H-1-Benzopyran-3-carboxaldehyde, 7-methyl-4-oxo- CTK1D4361 (C11H8O3) is characterized by 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).
CATO manufactures 40682-97-1 4H-1-Benzopyran-3-carboxaldehyde, 7-methyl-4-oxo- CTK1D4361 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.
