Chemical Structure
Description
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.
CATO supplies Mca-Pro-Leu-Gly-Leu-Glu-Glu-Ala-Dap(Dnp)-NH2 (CAS 891198-38-2), a certified reference material (molecular formula C53H70N12O20, MW 1195.21 g/mol) for analytical method development and quality control.
The molecular framework of Mca-Pro-Leu-Gly-Leu-Glu-Glu-Ala-Dap(Dnp)-NH2 (C53H70N12O20) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
