Chemical Structure

3-Fluoropyridine-2,6-diamine CAS 960138-28-7 chemical structure

Description

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.

3-Fluoropyridine-2,6-diamine (CAS 960138-28-7), molecular formula C5H6FN3 and molecular weight 127.12 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Fluoropyridine-2,6-diamine (C5H6FN3) contains a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 127.12 g/mol, it falls into the low-molecular-weight range. 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.
