Chemical Structure

n-Ethyl-5-fluoropyrimidin-2-amine CAS 1289386-10-2 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.

n-Ethyl-5-fluoropyrimidin-2-amine (CAS 1289386-10-2) is a high-purity analytical reference standard with the molecular formula C6H8FN3 and a molecular weight of 141.15 g/mol.

n-Ethyl-5-fluoropyrimidin-2-amine (C6H8FN3) contains a nitrile group, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
