Chemical Structure

Fmoc-Gly-D-Ser(psi(Me,Me)-Pro)-OH CAS 1998701-38-4 chemical structure

Description

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.

Fmoc-Gly-D-Ser(psi(Me,Me)-Pro)-OH (CAS 1998701-38-4) is a high-purity analytical reference standard with the molecular formula C23H24N2O6 and a molecular weight of 424.45 g/mol.

Fmoc-Gly-D-Ser(psi(Me,Me)-Pro)-OH (C23H24N2O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
