1-(2-Fluoroethyl)-1H-pyrazole-3-carbaldehyde CAS 1427013-72-6

Description

The occurrence of 1-(2-Fluoroethyl)-1H-pyrazole-3-carbaldehyde is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(2-Fluoroethyl)-1H-pyrazole-3-carbaldehyde (CAS 1427013-72-6) is a high-purity analytical reference standard with the molecular formula C6H7FN2O and a molecular weight of 142.13 g/mol.

The molecular framework of 1-(2-Fluoroethyl)-1H-pyrazole-3-carbaldehyde (C6H7FN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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.
