Chemical Structure
Description
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.
1-(2-Aminoethyl)-1,2-dihydropyridazine-3,6-dione hydrochloride (CAS 1255717-52-2), molecular formula C6H9N3O2HCl and molecular weight 191.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(2-Aminoethyl)-1,2-dihydropyridazine-3,6-dione hydrochloride (C6H9N3O2HCl) is characterized by an amide group, a carboxylic acid 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
