Chemical Structure
Description
As a certified reference material (CRM), 4-(3-Fluorophenyl)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.
4-(3-Fluorophenyl)oxazole (CAS 620971-54-2) is a high-purity analytical reference standard with the molecular formula C9H6FNO and a molecular weight of 163.15 g/mol.
The molecular framework of 4-(3-Fluorophenyl)oxazole (C9H6FNO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
