Chemical Structure
Description
4-(Chloromethyl)-2-(4-fluorophenyl)-1,3-oxazole (CAS 22091-39-0), molecular formula C10H7ClFNO and molecular weight 211.62 g/mol, is a CATO reference standard with documented purity and traceability.
4-(Chloromethyl)-2-(4-fluorophenyl)-1,3-oxazole (C10H7ClFNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 4-(Chloromethyl)-2-(4-fluorophenyl)-1,3-oxazole 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.
