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 4-(Difluoromethyl)dihydro-2H-pyran-2,6(3H)-dione (CAS 1706461-52-0), a certified reference material (molecular formula C6H6F2O3, MW 164.11 g/mol) for analytical method development and quality control.
The molecular framework of 4-(Difluoromethyl)dihydro-2H-pyran-2,6(3H)-dione (C6H6F2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 4-(Difluoromethyl)dihydro-2H-pyran-2,6(3H)-dione 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.
