Chemical Structure
Description
1,3-Difluoro-2,4-pentanedione (CAS 87498-27-9), molecular formula C5H6F2O2 and molecular weight 136.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 1,3-Difluoro-2,4-pentanedione is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,3-Difluoro-2,4-pentanedione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
