Chemical Structure
Description
Owing to a nitrile group, iodine substitution, 4-Iodo-1,3-dimethyl-1h-pyrazol-5-amine is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.04 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.
4-Iodo-1,3-dimethyl-1h-pyrazol-5-amine (CAS 75092-40-9), molecular formula C5H8IN3 and molecular weight 237.04 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
