As a certified reference material (CRM), 3-Bromo-4-((2-chloro-4-fluorobenzyl)oxy)-5-methoxybenzaldehyde 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.
3-Bromo-4-((2-chloro-4-fluorobenzyl)oxy)-5-methoxybenzaldehyde (CAS 1154005-99-8), molecular formula C15H11BrClFO3 and molecular weight 373.60 g/mol, is a CATO reference standard with documented purity and traceability.
3-Bromo-4-((2-chloro-4-fluorobenzyl)oxy)-5-methoxybenzaldehyde (C15H11BrClFO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, a polycyclic aromatic system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
