Description
CATO manufactures (2S,4R)-N-Fmoc-4-difluoromethoxy-Pro-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.
(2S,4R)-N-Fmoc-4-difluoromethoxy-Pro-OH (CAS 2382632-22-4) is a high-purity analytical reference standard with the molecular formula C21H19F2NO5 and a molecular weight of 403.38 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (2S,4R)-N-Fmoc-4-difluoromethoxy-Pro-OH is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 403.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
