The occurrence of 2-Chloro-5-[(2,4-dimethylphenoxy)methyl]-1,3-thiazole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Chloro-5-[(2,4-dimethylphenoxy)methyl]-1,3-thiazole (CAS 303987-44-2) is a high-purity analytical reference standard with the molecular formula C12H12ClNOS and a molecular weight of 253.75 g/mol.
The molecular framework of 2-Chloro-5-[(2,4-dimethylphenoxy)methyl]-1,3-thiazole (C12H12ClNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
