Chemical Structure
Description
Structurally, H-Gly-Glu-Gly-Phe-Leu-Gly-D-Phe-Leu-OH (C41H58N8O11) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 838.95 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
H-Gly-Glu-Gly-Phe-Leu-Gly-D-Phe-Leu-OH (CAS 61393-34-8) is a high-purity analytical reference standard with the molecular formula C41H58N8O11 and a molecular weight of 838.95 g/mol.
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.
