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-[2-(ethanesulfonyl)ethyl]-3-iodo-4-methyl-1h-pyrazole.
1-[2-(ethanesulfonyl)ethyl]-3-iodo-4-methyl-1h-pyrazole (CAS 1515965-05-5) is a high-purity analytical reference standard with the molecular formula C8H13IN2O2S and a molecular weight of 328.17 g/mol.
1-[2-(ethanesulfonyl)ethyl]-3-iodo-4-methyl-1h-pyrazole (C8H13IN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
