Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 236.01 g/mol gives acetyl-4-iodo-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies acetyl-4-iodo-1H-pyrazole (CAS 98027-52-2), a certified reference material (molecular formula C5H5IN2O, MW 236.01 g/mol) for analytical method development and quality control.
Based on its molecular formula C5H5IN2O, acetyl-4-iodo-1H-pyrazole contains an amide group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.01 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.
