Chemical Structure

4-amino-6-chloro-2,3-dihydropyridazin-3-one CAS 14704-64-4 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.

4-amino-6-chloro-2,3-dihydropyridazin-3-one (CAS 14704-64-4), molecular formula C4H8ClN3O and molecular weight 149.58 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-amino-6-chloro-2,3-dihydropyridazin-3-one (C4H8ClN3O) is characterized by 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.

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.
