Chemical Structure
Description
The occurrence of Suc-Ala-Leu-Pro-Phe-pNA (L-1620.0050) is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Suc-Ala-Leu-Pro-Phe-pNA (L-1620.0050) (CAS 128802-78-8) is a high-purity analytical reference standard with the molecular formula C33H42N6O9 and a molecular weight of 666.72 g/mol.
Suc-Ala-Leu-Pro-Phe-pNA (L-1620.0050) (C33H42N6O9) 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.
