Chemical Structure
Description
2-(4-Chlorophenyl)-2-{6-[(4-chlorophenyl)sulfanyl]pyridazin-3-yl}acetamide (CAS 303997-46-8), molecular formula C18H13Cl2N3OS and molecular weight 390.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 2-(4-Chlorophenyl)-2-{6-[(4-chlorophenyl)sulfanyl]pyridazin-3-yl}acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 390.29 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}acetamide 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.
