Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 221.18 g/mol gives 2-(4-Fluorophenyl)-5-methyloxazole-4-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(4-Fluorophenyl)-5-methyloxazole-4-carboxylic acid (CAS 61152-03-2) is a high-purity analytical reference standard with the molecular formula C11H8FNO3 and a molecular weight of 221.18 g/mol.
2-(4-Fluorophenyl)-5-methyloxazole-4-carboxylic acid (C11H8FNO3) 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, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
