(R)-2-(4-((2-Aminobutyl)amino)pyrimidin-2-yl)-4-(1-methyl-1H-pyrazol-4-yl)phenol CAS 956123-34-5 chemical structure

Description

The occurrence of (R)-2-(4-((2-Aminobutyl)amino)pyrimidin-2-yl)-4-(1-methyl-1H-pyrazol-4-yl)phenol is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(R)-2-(4-((2-Aminobutyl)amino)pyrimidin-2-yl)-4-(1-methyl-1H-pyrazol-4-yl)phenol (CAS 956123-34-5), molecular formula C18H22N6OHCl and molecular weight 374.87 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (R)-2-(4-((2-Aminobutyl)amino)pyrimidin-2-yl)-4-(1-methyl-1H-pyrazol-4-yl)phenol (C18H22N6OHCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 374.87 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
