Chemical Structure

Mca-Glu-Asp-Ala-Ser-Thr-Pro-Cys-OH CAS 291297-58-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Mca-Glu-Asp-Ala-Ser-Thr-Pro-Cys-OH.

Mca-Glu-Asp-Ala-Ser-Thr-Pro-Cys-OH (CAS 291297-58-0), molecular formula C39H51N7O18S and molecular weight 937.92 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C39H51N7O18S, Mca-Glu-Asp-Ala-Ser-Thr-Pro-Cys-OH contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 937.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
