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 Diethyl (3,4-difluorobenzyl)phosphonate (CAS 451455-95-1), a certified reference material (molecular formula C11H15F2O3P, MW 264.21 g/mol) for analytical method development and quality control.
Structurally, Diethyl (3,4-difluorobenzyl)phosphonate (C11H15F2O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 264.21 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), Diethyl (3,4-difluorobenzyl)phosphonate 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.
