Chemical Structure
Description
2-(4-Chlorophenyl)-2-(6-(phenylthio)pyridazin-3-yl)acetonitrile (CAS 303997-39-9) is a high-purity analytical reference standard with the molecular formula C18H12ClN3S and a molecular weight of 337.83 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 2-(4-Chlorophenyl)-2-(6-(phenylthio)pyridazin-3-yl)acetonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 337.83 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(4-Chlorophenyl)-2-(6-(phenylthio)pyridazin-3-yl)acetonitrile 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.
