Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 234.17 g/mol gives 3,4-Dimethoxy-2-(trifluoromethyl)benzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,4-Dimethoxy-2-(trifluoromethyl)benzaldehyde (CAS 138490-96-7), a certified reference material (molecular formula C10H9F3O3, MW 234.17 g/mol) for analytical method development and quality control.
The molecular framework of 3,4-Dimethoxy-2-(trifluoromethyl)benzaldehyde (C10H9F3O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
