Chemical Structure
Description
The occurrence of tert-Butyl (1R*,4R*)-4-(1-oxoisoindolin-2-yl)cyclohexylcarbamate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
tert-Butyl (1R*,4R*)-4-(1-oxoisoindolin-2-yl)cyclohexylcarbamate (CAS 412357-35-8), molecular formula C19H26N2O3 and molecular weight 330.42 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, tert-Butyl (1R*,4R*)-4-(1-oxoisoindolin-2-yl)cyclohexylcarbamate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
