Chemical Structure
Description
The occurrence of 2-(4-Chlorophenyl)-2-{6-[(4-chlorophenyl)sulfanyl]pyridazin-3-yl}acetonitrile 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-(4-Chlorophenyl)-2-{6-[(4-chlorophenyl)sulfanyl]pyridazin-3-yl}acetonitrile (CAS 303997-43-5), molecular formula C18H11Cl2N3S and molecular weight 372.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 2-(4-Chlorophenyl)-2-{6-[(4-chlorophenyl)sulfanyl]pyridazin-3-yl}acetonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.27 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-[(4-chlorophenyl)sulfanyl]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.
