Chemical Structure

4-Fluoro-5-hydroxypyrimidine CAS 1803770-59-3 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.

4-Fluoro-5-hydroxypyrimidine (CAS 1803770-59-3), molecular formula C4H3FN2O and molecular weight 114.08 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, 4-Fluoro-5-hydroxypyrimidine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 114.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
