Chemical Structure
Description
5-(2,4,6-Trifluorophenyl)oxazole (CAS 2002792-02-9), molecular formula C9H4F3NO and molecular weight 199.13 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H4F3NO, 5-(2,4,6-Trifluorophenyl)oxazole contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 199.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-(2,4,6-Trifluorophenyl)oxazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
