4-[3,5-dichloro-2-(difluoromethoxy)phenyl]-2-methyl-1,3-thiazole (CAS 790263-52-4) is a high-purity analytical reference standard with the molecular formula C11H7Cl2F2NOS and a molecular weight of 310.15 g/mol.
The molecular framework of 4-[3,5-dichloro-2-(difluoromethoxy)phenyl]-2-methyl-1,3-thiazole (C11H7Cl2F2NOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/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.
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.
