Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Ethyl-4-iodo-3-isopropyl-1H-pyrazole.
1-Ethyl-4-iodo-3-isopropyl-1H-pyrazole (CAS 1354705-60-4) is a high-purity analytical reference standard with the molecular formula C8H13IN2 and a molecular weight of 264.11 g/mol.
Based on its molecular formula C8H13IN2, 1-Ethyl-4-iodo-3-isopropyl-1H-pyrazole contains a nitrile group, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 264.11 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.
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.
