Chemical Structure
Description
H-Val-Pro-Leu-Ser-Leu-Tyr-Ser-Gly-OH (CAS 425632-67-3), molecular formula C39H62N8O12 and molecular weight 835.00 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, H-Val-Pro-Leu-Ser-Leu-Tyr-Ser-Gly-OH (C39H62N8O12) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 835.00 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
