Description
CATO manufactures 2-(4-Chlorophenyl)-2-[6-(phenylsulfanyl)pyridazin-3-yl]acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
2-(4-Chlorophenyl)-2-[6-(phenylsulfanyl)pyridazin-3-yl]acetamide (CAS 303997-45-7) is a high-purity analytical reference standard with the molecular formula C18H14ClN3OS and a molecular weight of 355.84 g/mol.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 2-(4-Chlorophenyl)-2-[6-(phenylsulfanyl)pyridazin-3-yl]acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 355.84 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
