Chemical Structure
Description
2-[4-Bromo-2-(tert-butyl)phenoxy]acetic acid 3158AE 425372-86-7 C12H15BrO3 (CAS 425372-86-7), molecular formula C12H15BrO3 and molecular weight 287.15 g/mol, is a CATO reference standard with documented purity and traceability.
2-[4-Bromo-2-(tert-butyl)phenoxy]acetic acid 3158AE 425372-86-7 C12H15BrO3 (C12H15BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
As a certified reference material (CRM), 2-[4-Bromo-2-(tert-butyl)phenoxy]acetic acid 3158AE 425372-86-7 C12H15BrO3 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.
