Chemical Structure

Fmoc-β-Ala-D-Aph(Cbm)-OH CAS CATO-CPTD789022 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 516.55 g/mol gives Fmoc-β-Ala-D-Aph(Cbm)-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Fmoc-β-Ala-D-Aph(Cbm)-OH (CAS CATO-CPTD789022), molecular formula C28H28N4O6 and molecular weight 516.55 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Fmoc-β-Ala-D-Aph(Cbm)-OH (C28H28N4O6) is characterized by a steroid core, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
