Chemical Structure
Description
The occurrence of Fmoc-β-Ala-Ser(tBu)-OH is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Fmoc-β-Ala-Ser(tBu)-OH (CAS CATO-CPTD788348), molecular formula C25H30N2O6 and molecular weight 454.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Fmoc-β-Ala-Ser(tBu)-OH (C25H30N2O6) is characterized by a flavonoid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 manufactures Fmoc-β-Ala-Ser(tBu)-OH under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
