Chemical Structure
Description
1-[(3-fluorophenyl)methyl]-3,5-dimethyl-1h-pyrazol-4-amine dihydrochloride (CAS 1185360-65-9), molecular formula C12H14FN3HCl and molecular weight 255.72 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H14FN3HCl, 1-[(3-fluorophenyl)methyl]-3,5-dimethyl-1h-pyrazol-4-amine dihydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 255.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
