1-(5-Chloro-1-ethyl-6-oxo-1,6-dihydropyridazin-4-yl)piperidine-4-carboxylic acid (CAS 1082393-19-8), molecular formula C12H16ClN3O3 and molecular weight 285.73 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(5-Chloro-1-ethyl-6-oxo-1,6-dihydropyridazin-4-yl)piperidine-4-carboxylic acid (C12H16ClN3O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
