Chemical Structure
Description
5-(4-Fluorophenyl)-1,2-oxazole-3-carbaldehyde (CAS 640292-06-4), molecular formula C10H6FNO2 and molecular weight 191.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(4-Fluorophenyl)-1,2-oxazole-3-carbaldehyde (C10H6FNO2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 5-(4-Fluorophenyl)-1,2-oxazole-3-carbaldehyde 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.
