Chemical Structure
Description
The occurrence of N-Fmoc-L-threonine Allyl Ester 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.
N-Fmoc-L-threonine Allyl Ester (CAS 136523-92-7) is a high-purity analytical reference standard with the molecular formula C22H23NO5 and a molecular weight of 381.42 g/mol.
The molecular framework of N-Fmoc-L-threonine Allyl Ester (C22H23NO5) 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. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-Fmoc-L-threonine Allyl Ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
