Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 348.41 g/mol gives Tert-butyl (4-(5-fluoro-1-oxoisoindolin-2-yl)cyclohexyl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tert-butyl (4-(5-fluoro-1-oxoisoindolin-2-yl)cyclohexyl)carbamate (CAS 1707367-80-3), a certified reference material (molecular formula C19H25FN2O3, MW 348.41 g/mol) for analytical method development and quality control.
Tert-butyl (4-(5-fluoro-1-oxoisoindolin-2-yl)cyclohexyl)carbamate (C19H25FN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
