Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Chloro-N-(3-(3-(4-fluorophenyl)-6-oxopyridazin-1(6H)-yl)propyl)benzamide.
2-Chloro-N-(3-(3-(4-fluorophenyl)-6-oxopyridazin-1(6H)-yl)propyl)benzamide (CAS 1040669-43-9), molecular formula C20H17ClFN3O2 and molecular weight 385.82 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Chloro-N-(3-(3-(4-fluorophenyl)-6-oxopyridazin-1(6H)-yl)propyl)benzamide (C20H17ClFN3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 385.82 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
