2-(1-(prop-2-yn-1-yl)-3-(trifluoromethyl)-1h-pyrazol-4-yl)ethan-1-ol CAS 1788672-91-2

Description

Compared with other compounds in its class, the molecular weight of 218.18 g/mol gives 2-(1-(prop-2-yn-1-yl)-3-(trifluoromethyl)-1h-pyrazol-4-yl)ethan-1-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(1-(prop-2-yn-1-yl)-3-(trifluoromethyl)-1h-pyrazol-4-yl)ethan-1-ol (CAS 1788672-91-2), molecular formula C9H9F3N2O and molecular weight 218.18 g/mol, is a CATO reference standard with documented purity and traceability.

2-(1-(prop-2-yn-1-yl)-3-(trifluoromethyl)-1h-pyrazol-4-yl)ethan-1-ol (C9H9F3N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
