Chemical Structure

1,1-Difluoroacetylacetone CAS 41739-23-5 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.

1,1-Difluoroacetylacetone (CAS 41739-23-5), molecular formula C5H6F2O2 and molecular weight 136.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,1-Difluoroacetylacetone (C5H6F2O2) 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 1,1-Difluoroacetylacetone 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.
