4-[5-({[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}methyl)-4,5-dihydro-1,2-oxazol-3-yl]pyrimidin-2-amine CAS 344277-07-2

Description

4-[5-({[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}methyl)-4,5-dihydro-1,2-oxazol-3-yl]pyrimidin-2-amine (CAS 344277-07-2) is a high-purity analytical reference standard with the molecular formula C14H12ClF3N6O and a molecular weight of 372.73 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 4-[5-({[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}methyl)-4,5-dihydro-1,2-oxazol-3-yl]pyrimidin-2-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.73 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.
