4-(4-Chloro-2-methylphenoxy)-5-methoxy-2-phenylpyrimidine (CAS 478029-69-5), molecular formula C18H15ClN2O2 and molecular weight 326.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(4-Chloro-2-methylphenoxy)-5-methoxy-2-phenylpyrimidine (C18H15ClN2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
