Description
CATO manufactures Diethyl (2,4,5-trifluorobenzyl)phosphonate 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.
Diethyl (2,4,5-trifluorobenzyl)phosphonate (CAS 1638764-10-9) is a high-purity analytical reference standard with the molecular formula C11H14F3O3P and a molecular weight of 282.20 g/mol.
Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Diethyl (2,4,5-trifluorobenzyl)phosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 282.20 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
