4-(Chloromethyl)-5-methyl-2-(4-methylphenyl)-1,3-oxazole (CAS 137090-44-9), molecular formula C12H12ClNO and molecular weight 221.68 g/mol, is a CATO reference standard with documented purity and traceability.
4-(Chloromethyl)-5-methyl-2-(4-methylphenyl)-1,3-oxazole (C12H12ClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
