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 3,5-Diethyl-4-iodo-1h-pyrazole (CAS 390356-27-1), a certified reference material (molecular formula C7H11IN2, MW 250.08 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H11IN2, 3,5-Diethyl-4-iodo-1h-pyrazole contains a nitrile group, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 250.08 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
