2-Benzyl-4-bromo-5-((4-fluorophenyl)thio)pyridazin-3(2H)-one CAS 565156-87-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Benzyl-4-bromo-5-((4-fluorophenyl)thio)pyridazin-3(2H)-one.

2-Benzyl-4-bromo-5-((4-fluorophenyl)thio)pyridazin-3(2H)-one (CAS 565156-87-8), molecular formula C17H12BrFN2OS and molecular weight 391.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Benzyl-4-bromo-5-((4-fluorophenyl)thio)pyridazin-3(2H)-one (C17H12BrFN2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 391.26 g/mol, it falls into the moderately-high-molecular-weight range. 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.
