The occurrence of 2-Methyl-4-(1H-pyrazol-4-yl)but-3-yn-2-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-Methyl-4-(1H-pyrazol-4-yl)but-3-yn-2-ol (CAS 116228-46-7), molecular formula C8H10N2O and molecular weight 150.18 g/mol, is a CATO reference standard with documented purity and traceability.
2-Methyl-4-(1H-pyrazol-4-yl)but-3-yn-2-ol (C8H10N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
