N,N'-(3-fluoro-4-methyl-8-oxo-5,6,7,8-tetrahydronaphthalene-1,7-diyl)diacetamide (CAS 143655-70-3), molecular formula C15H17FN2O3 and molecular weight 292.31 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N,N'-(3-fluoro-4-methyl-8-oxo-5,6,7,8-tetrahydronaphthalene-1,7-diyl)diacetamide (C15H17FN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 292.31 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
