Chemical Structure
Description
5-Fluoro-2-methyl-4-(trifluoromethoxy)aniline (CAS 1706430-25-2), molecular formula C8H7F4NO and molecular weight 209.14 g/mol, is a CATO reference standard with documented purity and traceability.
5-Fluoro-2-methyl-4-(trifluoromethoxy)aniline (C8H7F4NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 5-Fluoro-2-methyl-4-(trifluoromethoxy)aniline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
