3-Chloro-4-(4-fluorophenoxy)aniline hydrochloride CAS 1030009-77-8

Description

Compared with other compounds in its class, the molecular weight of 274.12 g/mol gives 3-Chloro-4-(4-fluorophenoxy)aniline hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Chloro-4-(4-fluorophenoxy)aniline hydrochloride (CAS 1030009-77-8), molecular formula C12H9ClFNOHCl and molecular weight 274.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 3-Chloro-4-(4-fluorophenoxy)aniline hydrochloride is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 274.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
