Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 137.11 g/mol gives 4-Fluorobenzoxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Fluorobenzoxazole (CAS 1432059-01-2), a certified reference material (molecular formula C7H4FNO, MW 137.11 g/mol) for analytical method development and quality control.
Structurally, 4-Fluorobenzoxazole (C7H4FNO) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 137.11 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4-Fluorobenzoxazole 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.
