3-(2-Fluoro-phenyl)-isoxazole-5-carbaldehyde CAS 808740-52-5

Description

The occurrence of 3-(2-Fluoro-phenyl)-isoxazole-5-carbaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(2-Fluoro-phenyl)-isoxazole-5-carbaldehyde (CAS 808740-52-5), molecular formula C10H6FNO2 and molecular weight 191.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(2-Fluoro-phenyl)-isoxazole-5-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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 3-(2-Fluoro-phenyl)-isoxazole-5-carbaldehyde 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.
