p-Fluorobenzaldehyde oxime CAS 459-23-4

Description

The occurrence of p-Fluorobenzaldehyde oxime is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

p-Fluorobenzaldehyde oxime (CAS 459-23-4), molecular formula C7H6FNO and molecular weight 139.13 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H6FNO, p-Fluorobenzaldehyde oxime contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 139.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
