Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 157.19 g/mol gives 1-(2-Fluoroethyl)-3,5-dimethyl-1h-pyrazol-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(2-Fluoroethyl)-3,5-dimethyl-1h-pyrazol-4-amine (CAS 1427014-45-6) is a high-purity analytical reference standard with the molecular formula C7H12FN3 and a molecular weight of 157.19 g/mol.
1-(2-Fluoroethyl)-3,5-dimethyl-1h-pyrazol-4-amine (C7H12FN3) contains a nitrile group, 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.
