4-((2-Fluorophenoxy)methyl)-5-methylisoxazole-3-carboxylic acid (CAS 932917-74-3), molecular formula C12H10FNO4 and molecular weight 251.21 g/mol, is a CATO reference standard with documented purity and traceability.
4-((2-Fluorophenoxy)methyl)-5-methylisoxazole-3-carboxylic acid (C12H10FNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
