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 Tert-butyl (S)-(1-oxo-4-phenylbutan-2-yl)carbamate.
Tert-butyl (S)-(1-oxo-4-phenylbutan-2-yl)carbamate (CAS 1159634-66-8) is a high-purity analytical reference standard with the molecular formula C15H21NO3 and a molecular weight of 263.33 g/mol.
Tert-butyl (S)-(1-oxo-4-phenylbutan-2-yl)carbamate (C15H21NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).
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.
