Chemical Structure
Description
The occurrence of Diethyl (2-(3-bromophenyl)-1,1-difluoro-2-hydroxyethyl)phosphonate is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Diethyl (2-(3-bromophenyl)-1,1-difluoro-2-hydroxyethyl)phosphonate (CAS 1138782-93-0), a certified reference material (molecular formula C12H16BrF2O4P, MW 373.13 g/mol) for analytical method development and quality control.
The molecular framework of Diethyl (2-(3-bromophenyl)-1,1-difluoro-2-hydroxyethyl)phosphonate (C12H16BrF2O4P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine 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. 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), Diethyl (2-(3-bromophenyl)-1,1-difluoro-2-hydroxyethyl)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.
