Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Perfluorophenyl 4-(oxazol-5-yl)benzoate.
Perfluorophenyl 4-(oxazol-5-yl)benzoate (CAS 898288-91-0), molecular formula C16H6F5NO3 and molecular weight 355.22 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Perfluorophenyl 4-(oxazol-5-yl)benzoate (C16H6F5NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 355.22 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), Perfluorophenyl 4-(oxazol-5-yl)benzoate 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.
