1-Phenyl-3-(2-((6-(pyridin-4-ylamino)pyridazin-3-yl)amino)ethyl)urea CAS 1021213-56-8

Description

Compared with other compounds in its class, the molecular weight of 349.39 g/mol gives 1-Phenyl-3-(2-((6-(pyridin-4-ylamino)pyridazin-3-yl)amino)ethyl)urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Phenyl-3-(2-((6-(pyridin-4-ylamino)pyridazin-3-yl)amino)ethyl)urea (CAS 1021213-56-8) is a high-purity analytical reference standard with the molecular formula C18H19N7O and a molecular weight of 349.39 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1-Phenyl-3-(2-((6-(pyridin-4-ylamino)pyridazin-3-yl)amino)ethyl)urea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
