Chemical Structure

4-O-Benzyl-N-[(benzyloxy)carbonyl]-3-O-methyl-L-DOPA Methyl Ester CAS 881911-31-5 chemical structure

Description

4-O-Benzyl-N-[(benzyloxy)carbonyl]-3-O-methyl-L-DOPA Methyl Ester (C26H27NO6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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).

4-O-Benzyl-N-[(benzyloxy)carbonyl]-3-O-methyl-L-DOPA Methyl Ester (CAS 881911-31-5) is a high-purity analytical reference standard with the molecular formula C26H27NO6 and a molecular weight of 449.50 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.
