Chemical Structure
Description
The occurrence of Fmoc-2-Methoxy-D-Phenylalanine 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-2-Methoxy-D-Phenylalanine (CAS 170642-30-5) is a high-purity analytical reference standard with the molecular formula C25H23NO5 and a molecular weight of 417.45 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Fmoc-2-Methoxy-D-Phenylalanine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 417.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Fmoc-2-Methoxy-D-Phenylalanine 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.
