4-Chloro-6-((4-methoxybenzyl)oxy)-2-phenylpyrimidine CAS 1044559-74-1

Description

Compared with other compounds in its class, the molecular weight of 326.78 g/mol gives 4-Chloro-6-((4-methoxybenzyl)oxy)-2-phenylpyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Chloro-6-((4-methoxybenzyl)oxy)-2-phenylpyrimidine (CAS 1044559-74-1), molecular formula C18H15ClN2O2 and molecular weight 326.78 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-Chloro-6-((4-methoxybenzyl)oxy)-2-phenylpyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
