Chemical Structure
Description
The occurrence of Diethyl (3-iodobenzyl)phosphonate is closely related to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diethyl (3-iodobenzyl)phosphonate (CAS 261966-88-5), molecular formula C11H16IO3P and molecular weight 354.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Diethyl (3-iodobenzyl)phosphonate (C11H16IO3P) is characterized by a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Diethyl (3-iodobenzyl)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.
