4-(2-Chloro-4-fluorophenoxy)-6-phenylfuro[2,3-d]pyrimidine CAS 478063-45-5

Description

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 4-(2-Chloro-4-fluorophenoxy)-6-phenylfuro[2,3-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

4-(2-Chloro-4-fluorophenoxy)-6-phenylfuro[2,3-d]pyrimidine (CAS 478063-45-5) is a high-purity analytical reference standard with the molecular formula C18H10ClFN2O2 and a molecular weight of 340.74 g/mol.

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.
