Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-1-((R)-2-Amino-3-(1H-indol-3-yl)propanoyl)pyrrolidine-2-carboxylic acid.
(R)-1-((R)-2-Amino-3-(1H-indol-3-yl)propanoyl)pyrrolidine-2-carboxylic acid (CAS 821776-24-3) is a high-purity analytical reference standard with the molecular formula C16H19N3O3 and a molecular weight of 301.34 g/mol.
(R)-1-((R)-2-Amino-3-(1H-indol-3-yl)propanoyl)pyrrolidine-2-carboxylic acid (C16H19N3O3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
