Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3,6-Dichloro-4-phenylpyridazine (CAS 41373-96-0), molecular formula C10H6Cl2N2 and molecular weight 225.07 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H6Cl2N2, 3,6-Dichloro-4-phenylpyridazine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 225.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 3,6-Dichloro-4-phenylpyridazine 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.
