Chemical Structure
Description
Dibenzyl 2-fluoromalonate (CAS 133384-81-3), molecular formula C17H15FO4 and molecular weight 302.30 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C17H15FO4, Dibenzyl 2-fluoromalonate contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 302.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Dibenzyl 2-fluoromalonate 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.
