The occurrence of 2-(1-(3-Chlorophenyl)-1H-pyrazol-5-yl)thiazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(1-(3-Chlorophenyl)-1H-pyrazol-5-yl)thiazole (CAS 1269293-24-4), molecular formula C12H8ClN3S and molecular weight 261.73 g/mol, is a CATO reference standard with documented purity and traceability.
2-(1-(3-Chlorophenyl)-1H-pyrazol-5-yl)thiazole (C12H8ClN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 2-(1-(3-Chlorophenyl)-1H-pyrazol-5-yl)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.
