4-[(4-Chlorophenyl)sulfanyl]-6-{[(4-chlorophenyl)sulfanyl]methyl}-2-methylpyrimidine CAS 339278-78-3

Description

4-[(4-Chlorophenyl)sulfanyl]-6-{[(4-chlorophenyl)sulfanyl]methyl}-2-methylpyrimidine (CAS 339278-78-3), molecular formula C18H14Cl2N2S2 and molecular weight 393.35 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H14Cl2N2S2, 4-[(4-Chlorophenyl)sulfanyl]-6-{[(4-chlorophenyl)sulfanyl]methyl}-2-methylpyrimidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 393.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
