Chemical Structure
Description
2-((4-Bromophenyl)sulfonyl)-4-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidine (C14H13BrN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
CATO supplies 2-((4-Bromophenyl)sulfonyl)-4-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidine (CAS 343374-40-3), a certified reference material (molecular formula C14H13BrN2O2S, MW 353.23 g/mol) for analytical method development and quality control.
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.
