2,3-Difluoro-4-(phenyldiazenyl)phenol CAS 847872-04-2

Description

The occurrence of 2,3-Difluoro-4-(phenyldiazenyl)phenol 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.

2,3-Difluoro-4-(phenyldiazenyl)phenol (CAS 847872-04-2), molecular formula C12H8F2N2O and molecular weight 234.20 g/mol, is a CATO reference standard with documented purity and traceability.

2,3-Difluoro-4-(phenyldiazenyl)phenol (C12H8F2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
