Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Fmoc-3,4-dichloro-L-homophenylalanine.
Fmoc-3,4-dichloro-L-homophenylalanine (CAS 1260616-12-3), molecular formula C25H21Cl2NO4 and molecular weight 470.34 g/mol, is a CATO reference standard with documented purity and traceability.
Fmoc-3,4-dichloro-L-homophenylalanine (C25H21Cl2NO4) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Fmoc-3,4-dichloro-L-homophenylalanine 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.
