Chemical Structure

N,N-Dibenz­yloxy­carbonyl-lysine anhydride CAS 111142-54-2 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 N,N-Dibenz­yloxy­carbonyl-lysine anhydride.

N,N-Dibenz­yloxy­carbonyl-lysine anhydride (CAS 111142-54-2), molecular formula C44H50N4O11 and molecular weight 810.89 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C44H50N4O11, N,N-Dibenz­yloxy­carbonyl-lysine anhydride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 810.89 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
