Chemical Structure

Diethyl (4-bromo-2,5-dimethylbenzyl)phosphonate CAS 1170667-43-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 335.17 g/mol gives Diethyl (4-bromo-2,5-dimethylbenzyl)phosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Diethyl (4-bromo-2,5-dimethylbenzyl)phosphonate (CAS 1170667-43-2), molecular formula C13H20BrO3P and molecular weight 335.17 g/mol, is a CATO reference standard with documented purity and traceability.

Diethyl (4-bromo-2,5-dimethylbenzyl)phosphonate (C13H20BrO3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Diethyl (4-bromo-2,5-dimethylbenzyl)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.
