Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N-Fmoc-O-cyclopropyl-L-serine (CAS 2642331-45-9), a certified reference material (molecular formula C21H21NO5, MW 367.40 g/mol) for analytical method development and quality control.
The molecular framework of N-Fmoc-O-cyclopropyl-L-serine (C21H21NO5) 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.
As a certified reference material (CRM), N-Fmoc-O-cyclopropyl-L-serine 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.
