Description

The occurrence of 2-(Hydroxymethyl)-5-iodopyridazin-3(2H)-one is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(Hydroxymethyl)-5-iodopyridazin-3(2H)-one (CAS 825633-97-4), molecular formula C5H5IN2O2 and molecular weight 252.01 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H5IN2O2, 2-(Hydroxymethyl)-5-iodopyridazin-3(2H)-one contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 252.01 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
