4-(4-Chlorophenyl)-1-{5-[(4-chlorophenyl)sulfanyl]-4-phenyl-1,3-thiazol-2-yl}-1H-pyrazol-5-amine (CAS 956205-96-2), molecular formula C24H16Cl2N4S2 and molecular weight 495.45 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(4-Chlorophenyl)-1-{5-[(4-chlorophenyl)sulfanyl]-4-phenyl-1,3-thiazol-2-yl}-1H-pyrazol-5-amine (C24H16Cl2N4S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 495.45 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures 4-(4-Chlorophenyl)-1-{5-[(4-chlorophenyl)sulfanyl]-4-phenyl-1,3-thiazol-2-yl}-1H-pyrazol-5-amine 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.
