Description

The molecular framework of 113873-67-9 L-Glutamic acid, L-alpha-aspartyl-L-leucyl-L-alpha-aspartyl-L-valyl-L-prolyl-L-isoleucyl-L-prolylglycyl-L-arginyl-L-phenylalanyl-L-alpha-aspartyl-L-arginyl-L-arginyl-L-valyl-L-seryl-L-valyl-L-alanyl-L-alanyl- (C92H150N28O29) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

113873-67-9 L-Glutamic acid, L-alpha-aspartyl-L-leucyl-L-alpha-aspartyl-L-valyl-L-prolyl-L-isoleucyl-L-prolylglycyl-L-arginyl-L-phenylalanyl-L-alpha-aspartyl-L-arginyl-L-arginyl-L-valyl-L-seryl-L-valyl-L-alanyl-L-alanyl- (CAS 113873-67-9), molecular formula C92H150N28O29 and molecular weight 2112.35 g/mol, is a CATO reference standard with documented purity and traceability.

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.
