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 2-Ethyl-1-((5-isopropyl-2-methoxyphenyl)sulfonyl)-1H-imidazole.
CATO supplies 2-Ethyl-1-((5-isopropyl-2-methoxyphenyl)sulfonyl)-1H-imidazole (CAS 898644-99-0), a certified reference material (molecular formula C15H20N2O3S, MW 308.40 g/mol) for analytical method development and quality control.
2-Ethyl-1-((5-isopropyl-2-methoxyphenyl)sulfonyl)-1H-imidazole (C15H20N2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
