Chemical Structure

1-Methyl-3,5-diphenylpyridazine-4(1H)-thione CAS 59617-88-8 chemical structure

Description

1-Methyl-3,5-diphenylpyridazine-4(1H)-thione (C17H14N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

1-Methyl-3,5-diphenylpyridazine-4(1H)-thione (CAS 59617-88-8), molecular formula C17H14N2S and molecular weight 278.37 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 1-Methyl-3,5-diphenylpyridazine-4(1H)-thione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
