2-(1-Ethyl-1H-pyrazol-4-yl)pyrimidin-4-ol CAS 1365960-74-2

Description

The occurrence of 2-(1-Ethyl-1H-pyrazol-4-yl)pyrimidin-4-ol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(1-Ethyl-1H-pyrazol-4-yl)pyrimidin-4-ol (CAS 1365960-74-2) is a high-purity analytical reference standard with the molecular formula C9H10N4O and a molecular weight of 190.20 g/mol.

The molecular framework of 2-(1-Ethyl-1H-pyrazol-4-yl)pyrimidin-4-ol (C9H10N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. 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.
