Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Fmoc-3-cyano-D-phenylalanine.
Fmoc-3-cyano-D-phenylalanine (CAS 205526-37-0) is a high-purity analytical reference standard with the molecular formula C25H20N2O4 and a molecular weight of 412.44 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Fmoc-3-cyano-D-phenylalanine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 412.44 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-3-cyano-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.
