CATO supplies 3-(4-Chloro-5-methylpyrazol-1-yl)propylamine (CAS 951235-39-5), a certified reference material (molecular formula C7H12ClN3, MW 173.64 g/mol) for analytical method development and quality control.
3-(4-Chloro-5-methylpyrazol-1-yl)propylamine (C7H12ClN3) contains a nitrile group, chlorine 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.
