4-(4-Chlorophenoxy)-2-{[(2,6-dichlorophenyl)methyl]sulfanyl}-5-methoxypyrimidine CAS 338955-86-5

Description

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.

4-(4-Chlorophenoxy)-2-{[(2,6-dichlorophenyl)methyl]sulfanyl}-5-methoxypyrimidine (CAS 338955-86-5) is a high-purity analytical reference standard with the molecular formula C18H13Cl3N2O2S and a molecular weight of 427.73 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 4-(4-Chlorophenoxy)-2-{[(2,6-dichlorophenyl)methyl]sulfanyl}-5-methoxypyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 427.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
