5-(Benzylthio)-4-chloro-2-phenylpyridazin-3(2H)-one CAS 16461-34-0

Description

Compared with other compounds in its class, the molecular weight of 328.82 g/mol gives 5-(Benzylthio)-4-chloro-2-phenylpyridazin-3(2H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(Benzylthio)-4-chloro-2-phenylpyridazin-3(2H)-one (CAS 16461-34-0) is a high-purity analytical reference standard with the molecular formula C17H13ClN2OS and a molecular weight of 328.82 g/mol.

5-(Benzylthio)-4-chloro-2-phenylpyridazin-3(2H)-one (C17H13ClN2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
