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.

3-Amino-2-pyrazolin-5-one 3-Amino-5-hydroxypyrazole 3-Amino-5-pyrazolone 3-amino-1H-pyrazol-5(4H)-one 5-Amino-2,4-dihydro-3H-pyrazol-3-one 6126-22-3 NSC 30480 NSC 34806 NSC 50565 (CAS 6126-22-3) is a high-purity analytical reference standard with the molecular formula C3H9N3O and a molecular weight of 103.12 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, 3-Amino-2-pyrazolin-5-one 3-Amino-5-hydroxypyrazole 3-Amino-5-pyrazolone 3-amino-1H-pyrazol-5(4H)-one 5-Amino-2,4-dihydro-3H-pyrazol-3-one 6126-22-3 NSC 30480 NSC 34806 NSC 50565 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 103.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
