Chemical Structure

N-(tert-Butoxycarbonyl)-D-2-phenylglycine CAS 33125-05-2 chemical structure

Description

N-(tert-Butoxycarbonyl)-D-2-phenylglycine (C13H17NO4) contains a nitrogen-containing heterocyclic scaffold, an amide 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).

N-(tert-Butoxycarbonyl)-D-2-phenylglycine (CAS 33125-05-2) is a high-purity analytical reference standard with the molecular formula C13H17NO4 and a molecular weight of 251.28 g/mol.

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.
