Chemical Structure
Description
(2R)-2-Amino-1,2,3,4-tetrahydro-5,8-dimethoxy-2-naphthalenecarboxylic Acid Methyl Ester-13C (CAS 1346617-27-3) is a high-purity analytical reference standard with the molecular formula C13[13C]H19NO4 and a molecular weight of 266.30 g/mol.
(2R)-2-Amino-1,2,3,4-tetrahydro-5,8-dimethoxy-2-naphthalenecarboxylic Acid Methyl Ester-13C (C13[13C]H19NO4) 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).
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.
