Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Acetyl-4-((difluoroboranyl)oxy)-2H-chromen-2-one (CAS 873326-02-4) is a high-purity analytical reference standard with the molecular formula C11H7BF2O4 and a molecular weight of 251.98 g/mol.
The molecular framework of 3-Acetyl-4-((difluoroboranyl)oxy)-2H-chromen-2-one (C11H7BF2O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 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 3-Acetyl-4-((difluoroboranyl)oxy)-2H-chromen-2-one 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.
