6-Amino-2,3-difluorophenol CAS 115551-33-2

Description

The occurrence of 6-Amino-2,3-difluorophenol 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.

6-Amino-2,3-difluorophenol (CAS 115551-33-2), molecular formula C6H5F2NO and molecular weight 145.11 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 6-Amino-2,3-difluorophenol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.11 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.
