Description
Compared with other compounds in its class, the molecular weight of 456.32 g/mol gives Fmoc-3,4-dichloro-L-phenylalanine, 98% distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Fmoc-3,4-dichloro-L-phenylalanine, 98% (CAS 17766-59-5), molecular formula C24H19Cl2NO4 and molecular weight 456.32 g/mol, is a CATO reference standard with documented purity and traceability.
Fmoc-3,4-dichloro-L-phenylalanine, 98% (C24H19Cl2NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures Fmoc-3,4-dichloro-L-phenylalanine, 98% 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.
