Chemical Structure
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.
CATO supplies 4-(2-Iodoethyl)-3,5-dimethyl-1h-pyrazole (CAS 83467-29-2), a certified reference material (molecular formula C7H11IN2, MW 250.08 g/mol) for analytical method development and quality control.
Owing to a nitrile group, iodine substitution, 4-(2-Iodoethyl)-3,5-dimethyl-1h-pyrazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
