Chemical Structure
Description
The occurrence of 2-(5-Bromo-2-fluorophenyl)acetaldehyde is closely related to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(5-Bromo-2-fluorophenyl)acetaldehyde (CAS 844904-33-2) is a high-purity analytical reference standard with the molecular formula C8H6BrFO and a molecular weight of 217.04 g/mol.
The molecular framework of 2-(5-Bromo-2-fluorophenyl)acetaldehyde (C8H6BrFO) is characterized by a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-(5-Bromo-2-fluorophenyl)acetaldehyde 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.
