Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-((3,4,5-Trifluorophenoxy)methyl)benzaldehyde (CAS 1443353-70-5) is a high-purity analytical reference standard with the molecular formula C14H9F3O2 and a molecular weight of 266.22 g/mol.
The molecular framework of 3-((3,4,5-Trifluorophenoxy)methyl)benzaldehyde (C14H9F3O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 3-((3,4,5-Trifluorophenoxy)methyl)benzaldehyde 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.
