[1-(2-Fluoro-ethyl)-1h-pyrazol-3-yl]-methanol CAS 1427021-99-5

Description

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.

[1-(2-Fluoro-ethyl)-1h-pyrazol-3-yl]-methanol (CAS 1427021-99-5), molecular formula C6H9FN2O and molecular weight 144.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of [1-(2-Fluoro-ethyl)-1h-pyrazol-3-yl]-methanol (C6H9FN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 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.
