Description
CATO manufactures 2,4-Dichloro-5-(difluoromethyl)-1,3-thiazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
2,4-Dichloro-5-(difluoromethyl)-1,3-thiazole (CAS 105315-43-3) is a high-purity analytical reference standard with the molecular formula C4HCl2F2NS and a molecular weight of 204.03 g/mol.
2,4-Dichloro-5-(difluoromethyl)-1,3-thiazole (C4HCl2F2NS) contains a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
