Description
pGlu-Val-Leu-Val-Ser-Pro-Ala-Phe-Tyr-Gly-Val-Val-Pro-Ala-Val-Val-Pro-Ala-Val-Gln-Pro-Gly-Tyr-Val-Ala-Ala-Thr-Arg-Gly-Ser-Leu-His-Val-Ala-Pro-Leu-Pro-Gly-Asn-Val-Pro-Tyr-Ala-Ser-His-His-Leu-Asn-Leu-Ala-Pro-Ala-Pro-Gly-Thr-Leu (CAS CATO-CPTD788763) is a high-purity analytical reference standard with the molecular formula C263H404N68O69 and a molecular weight of 5622.44 g/mol.
The molecular framework of pGlu-Val-Leu-Val-Ser-Pro-Ala-Phe-Tyr-Gly-Val-Val-Pro-Ala-Val-Val-Pro-Ala-Val-Gln-Pro-Gly-Tyr-Val-Ala-Ala-Thr-Arg-Gly-Ser-Leu-His-Val-Ala-Pro-Leu-Pro-Gly-Asn-Val-Pro-Tyr-Ala-Ser-His-His-Leu-Asn-Leu-Ala-Pro-Ala-Pro-Gly-Thr-Leu (C263H404N68O69) 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).
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.
