(3-(Difluoromethyl)isoxazol-5-yl)methanamine CAS 2118317-99-8

Description

The occurrence of (3-(Difluoromethyl)isoxazol-5-yl)methanamine is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3-(Difluoromethyl)isoxazol-5-yl)methanamine (CAS 2118317-99-8) is a high-purity analytical reference standard with the molecular formula C5H6F2N2O and a molecular weight of 148.11 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (3-(Difluoromethyl)isoxazol-5-yl)methanamine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.11 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.
