Ethyl 5-bromo-4-ethoxy-2,3-difluorobenzoate CAS 2484888-89-1

Description

As a certified reference material (CRM), Ethyl 5-bromo-4-ethoxy-2,3-difluorobenzoate 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.

Ethyl 5-bromo-4-ethoxy-2,3-difluorobenzoate (CAS 2484888-89-1), molecular formula C11H11BrF2O3 and molecular weight 309.10 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 5-bromo-4-ethoxy-2,3-difluorobenzoate (C11H11BrF2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. 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.

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.
